How to encrypt Apple 1 1 SMS?

At present, Apple has not directly provided the iPhone with the function of application encryption. However, if you want to prevent others from accessing your application (such as preventing others from accessing your WeChat, QQ, etc.). ), you can use the "screen usage time" function to limit. The following is the detailed setting method:

1. Open iPhone settings-screen usage time. If this is your first time setting up, please select "This is my iPhone".

2. In this interface, click "Set screen usage time password", and then enter the password. This password is equivalent to the Application Lock password.

Tip: Please remember your password, otherwise you can only erase all the data.
