How to prevent iMessage from popping up on Mac? Follow the steps below.

1. On your Mac, open System Preferences through the Apple Menu, Launchpad or Spotlight, etc.

2. Click Notifications.

How to create strong passwords

When you choose to lock iMessage and other Mac apps with password, it’s crucial to select a strong one. If the password is weak or easy to guess, other people may easily figure out the password and successfully open a locked app. If so, your efforts protect privacy will go in vain. The tips below may be of some help.

  • It is better to set the password more than 8 characters.
  • Try to add some special symbols like *&^%$#.
  • Never put your birth date, phone number, vehicle Number, etc. as your password when the protected object is very significant.
  • Use passwords that include combinations of uppercase, lowercase, letters and numbers.
  • Avoid using passwords like 12345678, password, admin, 111111, 123123, iloveyou, aaaaaa, qwerty, photoshop, etc.

It’s not enough to just set a complex password. It’s equally important to always remember it correctly. If you forget the password when using tools like AppCrypt, it will be impossible or difficult to retrieve it.

How to lock apps on iOS devices

Devices with iOS 12 or later come with a solution to lock apps. The Screen Time feature can be used to restrict access to individual apps (such as iMessage and Snapchat) or a whole category (such as Entertainment) of apps with passcode.

It’s also possible to lock apps with built-in features like Guided Access or third-party apps. If an app supports Touch ID or Face ID, it can also be protected with fingerprint or facial recognition. To find out more, check out this guide.

      When someone tries to access your password protected application, AppCrypt will ask he or she to enter a password. If the password is wrong, system will keep a record automatically with photo, time and reason.

    I know there are some paid apps can add password protection to individual applications, but are there any free ways to do that?

      As far as I know, there are no free ways to password protection individual applications. But you can use Mac's built-in Parental Control to set restriction on some apps.
