OppoA32, why do I need authentication to delete SMS?

Security issues. This function cannot be turned off, it is set by the system, and the frequency of verification can be modified. Verify your identity with your fingerprint, open the settings in your mobile phone, find your fingerprint, face and password, and select fingerprint to set your fingerprint. If the screen lock password is set, you need to enter the screen lock password first, then enter the fingerprint settings and select the fingerprint as an option. Turn on the options of installation and SMS deduction verification, and you can directly use fingerprint verification when installing the software.
