The Whats app is launching a new security feature that is very simple and useful. Wats app IOS users will now save their chat with Touch ID and FaceID. This feature will be issued later for Android. From this feature, users will be able to access their chat after biometric verification.
This feature is best for users whose mobile has personal data and they have to unlock the mobile phone for phone calls etc.
To use this feature, you will need to select a biometric security option by going to Settings> Account> Privacy> Screen Lock. You can choose the time you want, after which the app automatically loses.
Remember to use the TouchID feature to use the IOS 9 or the latest and FaceID feature in your phone, your mobile should have an IOS 12 or modern installed.
The Wats app did not tell the launch date for this feature for Android, but it is said that this feature is in the development process for Android. Upon this feature, Endroid users can save Wats app or other apps by installing various app lock applications from the Play Store.
