The specific operation method is as follows:

1. Enter the phone settings-screen lock, password and fingerprint-private password, and make corresponding settings according to the prompts to open private SMS.

2. You can also use MIUI's private SMS function to set SMS encryption for personal contacts: in the SMS application interface, alternately pull down the SMS list with two fingers to enter the private SMS settings.

P.S. If you can't find the received or sent SMS in the SMS list, you can enter the private SMS to find it.
