Because customers often encounter situations where users forget their passwords, causing users to send them back to the customer, this function needs to be developed.
This function is implemented on Android8—Android13 respectively.
First of all, when setting a universal password, at least two points must be considered:
1. Verification of lock screen interface
2. Verification in setting
The idea is simple:
When setting the password, the password set by the user is obtained and stored. When the user enters the universal password, the universal password is replaced with the correct password.
Android9 adds universal password
