Password protect WhatsApp messenger on Android, iOS and Windows

password, iphone

Locking any application with a password is one of the most effective ways to increase the privacy level of a user who trusts the software with their information. The article will describe the methods and means of installing protection against the gaze of strangers, applicable to the WhatsApp messenger on an Android device, iPhone and Windows-PC.

Screen Time (iOS 12 and above)

If for some reason blocking WhatsApp using “Touch ID” or “Face ID” is not suitable, you can restrict access to the messenger using the functionality of the “Screen Time” software module, which first appeared on the iPhone with the release of iOS 12.

    Open “Settings” iOS and go to the section “Screen Time”.

If previously the control over the application usage time was not used, tap “Turn on Screen Time”, and then “Next” and “This is my iPhone“.

Scroll through the list of available options and touch “Use a password code”. Next, we enter four numbers twice, which will serve as a password for access to the limited Screen Time features, and in our case, to the WhatsApp messenger.

Now we launch WhatsApp and use it for a minute or so, or just wait a little by opening the application.

We return to “Screen Time” and tap on the area that displays the total screen time. Now click on the item “WhatsApp” in the list “FREQUENTLY USED”.

Next, we call the “Add limit” function, which becomes available if you scroll the information on the screen all the way up. Enter the digital code specified when performing the item.

In the “Time” area, set the limit “0 h 1 min” and then tap “Add” at the top of the screen on the right.

This completes the installation of restrictions. The WhatsApp icon on the iPhone desktop will change its appearance, and when you try to launch the messenger, the message “Time limit” will appear.

To gain access to the application on the above screen, you need to tap “Ask to extend the term”, then click “Enter the password code”.

Now we choose the time during which WhatsApp will work without restrictions, that is, to open the application, you will not need to enter a secret combination of numbers.


Unfortunately, neither the WhatsApp PC client nor the Windows operating system provides the function of protecting individual applications from unauthorized access by setting a password. In addition, third-party software (Exe Password (Exe Guarder), Game Protector), which demonstrates its effectiveness in blocking various software, turns out to be powerless in relation to WhatsApp, or rather, as a result of its work, it causes the messenger to crash.

Thus, to persons using WhatsApp from a computer to which strangers have access, it remains only to recommend setting up an account in Windows and using its password lock, which implies protection against unauthorized access of all installed software, including the messenger.


WhatsApp for Android users, when solving the problem of ensuring the protection of the messenger by setting a password to open it, have the opportunity to go one of really many ways. Despite the fact that the blocking function is not provided for in the client application for this OS, it will not be difficult to install protection on WhatsApp using third-party software. You need to choose a suitable tool from a wide list of available ones, for example, in the Google Play Store. The most effective of these products, as well as the solution to the issue under consideration with their help, are described in a separate material on our website.

Among other things, the owners of modern smartphones Xiaomi, Redmi, Huawei, Honor, Meizu, Asus and others that operate under the appropriate Android shells MIUI, EMUI, FlymeOS, ZEN UI, etc. it is recommended to pay attention to the tools of the category “Application Protection” integrated into the system software of their devices. The use of this toolkit is generally described in the article available at the following link.

With regard to WhatsApp for iPhone, it is possible to set password protection by activating the lock in the “Settings” of the application, calling one of the iOS functions, as well as using specialized third-party software.

Third party software

In addition to the options suggested above, to solve the problem from the title of the article, iOS users can turn to specialized software created by third-party developers. Note that despite the abundance of offers in the Apple App Store, it was not possible to find free and at the same time effective tools with the functionality declared to achieve the desired result. Next, we will demonstrate how mediocre and at the same time paid applications with the function of setting a password on WhatsApp work, and as an example, we use Social Password Lock Manager from the developer Khadija Burhanpur.

    Click on the above link or open the App Store and find the Social Password Lock Manager application page through the search.

We purchase the program by tapping on the button with its cost, and then confirming the requests coming from the Apple App Store.

After completing the purchase, we wait for the download and installation of the program and then go to the iPhone Desktop.

We hide the WhatsApp icon from prying eyes, using for this purpose any folder on the Desktop of the smartphone. Those who do not know the specified way of working in iOS can use the instructions from the article, which describes in detail the process of hiding applications on the iPhone.

Launch WhatsLock and tap on the left icon under the words “Open WhatsApp:” on the screen.

Enter the four-digit PIN code twice, which will be required to start the messenger.

This completes the configuration of the tool, and in the future, WhatsApp is launched through WhatsLock by clicking on the icon-button with which the password was set in the previous paragraph of the instructions, and then entering a secret combination of numbers.

Additionally. Those who wish to change the key to access the messenger through WatsLock can use the “Change” button in the upper right corner of the screen of the latter. Here you will first need to enter the old pin code, and then twice the new one.

App lock on iOS

Apple doesn’t give third-party apps the same leeway as Google does with its Android, so you won’t find any universal blocking tools in the App Store. Instead, you should rely on some independent applications. Many of them can store confidential information and provide you with additional options.

One such example is the iPhone Notes app. You can lock individual notes by clicking on the Share button (inside a note) or long-pressing on it (in the list of notes), and then selecting “Lock Note”. Notes will be protected with Face ID, Touch ID, or PIN. You can add this security rule using Notes in your iOS settings.

WhatsApp is specially protected to keep prying eyes out of your messages. On the main screen, you need to select the menu “Settings”, “Account”, “Privacy” and “Screen lock”. You can then set up Touch ID or Face ID to secure access to your conversations. If any of these methods fail, the person will return to the phone screen lock page.

Another app with the same security measures is Dropbox. It will be convenient for those who do not want their little one to accidentally delete all files with a thoughtless finger press. Select “Account” from the menu, then click on the gear icon (top left), then set a password. You will also be given the option to use Touch ID or Face ID.

We can’t cover all iOS apps, but it’s worth looking at the most popular ones to see if there is an additional layer of protection inside. Evernote, Amazon, and PayPal are three more apps that can be locked using Touch ID or Face ID. Many banking apps now also have this feature, so even if someone gains access to your phone (with or without your permission), they won’t be able to get to all installed programs.

There are also several other tools you can take advantage of on iOS: they weren’t originally designed to protect apps, but they can do this. The first is the screen time that you can access from the settings menu: if you click on the Use screen time password option and then select app restrictions and set the daily app limit to zero hours zero minutes, you effectively protect yourself from prying eyes.

Second, there is Guided Access, which you’ll find in the Accessibility menu in Settings. After you turn it on, you need to open the application and press the side button or the Home button three times. In this case, you can only switch to another application by entering a specific phone passcode. This is ideal if you want your kids to play games on your phone, but keep your apps and data safe.

How to put a password on any application on your phone

In this article, we’ll talk about how to prevent strangers from spying on your messages, photos or emails if they accidentally or on purpose look at your phone screen.

We hope you have already set up a PIN, fingerprint or face verification (or all at once) on your phone. However, sometimes you want to add an extra layer of protection for certain applications.

How you want to apply this additional protection is entirely up to you. Some applications have this feature built in by default; otherwise, you will have to enlist the help of a third-party application. This process also differs depending on whether you are using Android or iOS, which is why we have divided our guide into two sections.

PASSWORD LOCK Any Apps on iPhone

Lock apps on Android

Android does allow third-party apps to control access to other apps, so you can install one of the blockers and block access to whichever apps you want. A password is usually required to gain access, although some locking tools may work with fingerprint sensors or facial recognition.

There are a number of such apps available on Android, as a quick search on the Google Play Store will confirm. However, taking into account that these apps need pretty deep access to your phone and apps because that’s what they need to get it to work. It is important to consider only those you fully trust.

Norton App Lock. fast, free and simple solution for Android. Screenshot: David Nyld

We have tried quite a few Android app blockers, and while we did not encounter any dangerous or suspicious activity, we did see apps that had a lot of bugs, ads, and additional features that were not necessary for reliable protection.

With all this in mind, Norton App Lock. this is the tool we recommend based on a brand you can trust. over, you don’t need to subscribe to any of the other Norton products to use App Lock. You can lock apps either with a password or with a picture.

Once you install Norton App Lock, it is immediately clear that its operation is very simple: you click on the applications you want to password protect, and that’s it. There is also the option to turn Norton App Lock on or off completely as needed. If you forget your password or picture, you can recover it using the Google account associated with your Android device.

You can pin apps on Android to prevent app switching. Screenshot: David Nyld

Some individual applications are also capable of setting additional protection. One of them, like for iOS, is Dropbox. If you go to “Settings” from the main menu of the application, you can select the item “Set password”. Every time you or someone else opens Dropbox on Android, you will need to enter a passcode.

Finally, you can use Android’s Lock Screen feature to keep your kids, loved one, friends, or coworkers inside one particular app. Open the Recently Included Apps screen (swipe up and long press on newer Android versions), then tap the icon at the top of the app you want to make the only one available, and then tap Enter Pin. Switching to any other application will not be possible until the correct password is entered.

Setting a password for an Android app in AppLock

In my opinion, AppLock is the best free application available for blocking the launch of other applications with a password (I will only note that for some reason the name of the application in the Play Store changes from time to time. either Smart AppLock, then just AppLock, and now AppLock FingerPrint, this may be a problem considering that there are similarly named but other applications).

Among the advantages are a wide range of functions (not only the password for the application), the Russian interface language and the absence of the requirement for a large number of permissions (you need to give only those that are really needed to use specific AppLock functions).

Using the application should not be difficult even for a novice owner of an Android device:

  • When you start AppLock for the first time, you need to create a PIN code that will be used to access the settings made in the application (to locks, etc.).
  • Immediately after entering and confirming the PIN, the “Applications” tab will open in AppLock, where, by pressing the “plus” button, you can mark all those applications that need to be blocked without the possibility of launching by unauthorized persons (when blocking the applications “Settings” and “Setup package “no one will be able to access the settings and install applications from the Play Store or APK file).
  • After you mark applications for the first time and click “Plus” (add to the list of protected), you will need to set permission to access the data. click “Apply” and then enable permission for AppLock.
  • As a result, you will see the applications you added in the blocked list. now you need to enter a pin code to launch them.
  • Two icons next to applications allow you to block notifications from these applications or display a fake startup error message instead of blocking (if you hold down the “Apply” button in the error message, a PIN-code entry window will appear and the application will start).
  • To use a text password for applications (as well as a graphic one), and not a PIN, go to the Settings tab in AppLock, then in the Security Settings section select the Lock Method and set the desired password type. An arbitrary text password is here designated as “Password (Combination)”.

Additional AppLock settings include:

  • Hiding an AppLock app from the app list.
  • Delete protection
  • Multi-password mode (separate password for each application).
  • Connection protection (you can put a password on calls, connections to mobile or Wi-Fi networks).
  • Blocking profiles (creating separate profiles, in each of which different applications are blocked with convenient switching between them).
  • On two separate tabs “Screen” and “Rotation” you can add applications for which the screen will be blocked from turning off and rotating. This is done in the same way as when setting a password for the application.

And this is not a complete list of available features. Overall, it’s a great, simple and well-functioning application. Among the shortcomings. sometimes not quite correct Russian translation of interface elements. Update: since the writing of the review, functions have appeared for taking a photo of guessing the password and unlocking with a fingerprint.

How to put a password on an Android app

One of the most common questions for owners of Android phones and tablets is how to put a password on the application, especially on messengers WhatsApp, Viber, VK and others.

Despite the fact that Android allows you to set restrictions on access to settings and installation of applications, as well as to the system itself, there are no built-in tools for setting a password for applications. Therefore, to protect against launching applications (as well as viewing notifications from them), you will have to use third-party utilities, which are discussed later in the review. See also: How to set a password on Android (unlock your device), Parental Controls on Android. Note: applications of this kind may cause “Overlays detected” error when asking for permissions by other applications, please consider this (more: Overlays detected on Android 6 and 7).

CM Locker Data Protection

CM Locker is another popular and completely free application that allows you to put a password on an Android application and more.

In the “Lock Screen and Applications” section of CM Locker, you can set a graphic or digital password that will be set to launch applications.

Section “Select items to block” allows you to set specific applications that will be blocked.

An interesting feature is “Attacker Photo”. When you enable this function, after a certain number of incorrect attempts to enter the password, the one who enters it will be photographed, and his photo will be sent to you by E-mail (and saved on the device).

CM Locker also has additional features, such as blocking notifications or protecting your phone or tablet from theft.

Also, as in the previous considered option, in CM Locker it is easy to set a password for the application, and the function of sending a photo is a great thing that allows you to see (and have proof) who, for example, wanted to read your correspondence in VK, Skype, Viber or Whatsapp.

Despite all of the above, I didn’t really like the CM Locker option for the following reasons:

  • A huge number of required permissions, requested immediately, and not as needed, as in AppLock (the need for some of which is not entirely clear).
  • Requirement on first launch of “Fix” detected “Threats” to device security without the option to skip this step. At the same time, some of these “threats” are my purposefully made settings for the operation of applications and Android.

This is not a complete list of tools that allow you to restrict the launch of applications on an Android device, but the options given are perhaps the most functional and fully cope with their task.

How to put a password on an iPhone application

How to put a password for an application in an iPhone is a completely natural question that arises among users of smartphones from Apple. The fact is that smartphones in modern life have begun to be used not only for their intended purpose. for telephone communications, but also as a repository of a huge amount of information: mail correspondence, application data, documents, photographs, bank card details and other personal data. Sometimes access to this data by third parties can lead to negative consequences, and users tend to forget the gadget while visiting, at work, in public places. Therefore, the desire to restrict access to data can be explained quite simply and can be important for any user.

How to put a password on an iPhone application using standard means

The easiest method to set a password is to use the default iPhone settings. Everything is quite simple: in the main menu of the smartphone you need to find the heading “Settings”, in it “General”. In the sub-item “Basic”, click on “Restrictions” and confirm by clicking on “Enable restrictions”. A field for entering an access code will appear, which is formed from 4 digits. After that, you determine the applications, the information in which needs to be protected. Confirmation of the settings is completed by clicking on “Save”.

With further use of the smartphone, the previously entered password will open access to information. When strangers try to access the contents of messages, mail, Whatsapp and other selected applications, they will also be asked for a password, so keep it secret and do not tell anyone. It should be borne in mind that professional hackers can try to bypass this protection, or they usually erase all information on a stolen phone, so it is advisable to store especially important data in other places.

As a password, it is advisable to use combinations that are understandable only to you, but difficult to understand and select by outsiders. Do not specify the date of birth, year of birth, usual combinations such as 1234 or 1111 as a password.

Third-party applications to install protection

In the App Store, applications are available for purchase, unfortunately, they do not support the ability to configure password access restrictions. Usually users are rescued by jailbreaks from the Applocker and iProtect services, which have programs for iOS in their assortment.

Apple has a policy of receiving apps only with purchases from the AppStore. The jailbreak method has significantly expanded the functionality of smartphones, removing restrictions on the file system for installing third-party applications.

That is, it will not work to put a password on Viber in the form of a code from a set of numbers. This means that if someone unlocks your iPhone, then nothing prevents him from entering Viber and reading the correspondence. This feature is absent not only on iPhones, but also on other operating systems and devices. However, there are alternative ways to resolve this issue.

Through special programs

You can set a password for one of the applications in your smartphone, including Viber, through special programs. There are many such programs, and they allow you to achieve security and preserve confidential information. They apply to all installed applications on the smartphone.

As mentioned earlier, there is no built-in password function in Viber. This feature is not available on the iPhone system either. That is, there is no personal password for individual applications. If you read about this somewhere, then this is just a fraudulent move to increase site traffic. But Viber has another standard option that allows you to protect your secret messages. The developers of Viber did their best to improve the interface and functionality of the application and introduced the “Hidden Chat” for concerned users. The essence of such a chat is that it is hidden in the general history of correspondence and is password protected.

If you want to use this function and set a password for correspondence, then follow the instructions:

  • Go to Viber.
  • Click on the chat with the correspondence you want to hide.
  • At the top, click on the button with three dots, a functional appears that is applied to this correspondence.
  • Choose “Hide chat”.
  • Enter your four-digit password and confirm it.

Using the “Hide chat” function, you can block an unlimited number of correspondences in your history.

When this function is activated, the text of the message and the username will not be displayed on the phone screen, but simply a signal about an incoming message in Viber. If necessary, you can cancel it in the settings. To access hidden correspondence, you must enter the password at the top of the Viber main page in the search bar among all chats.

Interact with an easy platform, the only regret is endless advertising.

Despite the fact that Apple pays so much attention to the security and privacy of its users, on the iPhone, you still cannot set a password for applications. If you give someone your unlocked smartphone, they can open any application on it.

Fortunately, with the new Screen Time feature, you can still protect your apps. The secret is to set limits for the apps you want to protect. Below we will tell you how everything is done. The method works with iOS 12 and newer.

How to set a password for an iPhone app

With the help of iPhone applications, it is possible to set a password for applications, files and folders stored on the internal memory of the iPhone.

It is impossible to restrict access to confidential information on iOS by hanging a separate lock on each icon with the application, which can be removed when entering a password. And the main reason for this is the limitations imposed by the operating system.

Therefore, you will have to act in other ways. with the help of special “safes” in which documents, photos, correspondence or even individual videos are placed, and then. they are hidden behind a password or a Touch ID or Face ID verification. The method may not be the most organic or fast, but it is working and time-tested.
