What should I do if I forget my password after encrypting a short message?

There is no default password for smartphone SMS password. You need to set a password for the first encryption.

If you forget your password, you can use the vivo assistant to back up relevant data on the computer side, and then go to Settings->; General->; Restore factory settings-> Clear all data to clear the password. This operation will lose all data on the mobile phone, including contacts, information and third-party programs installed by yourself, and the data on the SD card will not be lost. If there is no data to be backed up in the mobile phone, you can directly clear all the data in the mobile phone to clear the password.

Mobile phone factory settings recovery tutorial

First, turn off the phone completely. Then press the specific key combination to enter the recovery mode of the mobile phone. Because different mobile phones enter this mode in different ways, I will not list them one by one in this small series. You can get detailed help through the mobile phone manual or online search. In this small series, Huawei U8650 mobile phone is taken as an example to illustrate. The specific key combination is "turn up the volume"+"turn on". When it is held for more than 5 seconds, it will enter the recovery interface.

2. Use "Volume+"and "Volume-"to position the cursor to "Clear All Data", and then press "Power" or "Search" to confirm.

3. Select "Yes, clear data" in the next open interface and press "Power" or "Search" to confirm.

4. Using the same method, select "Clear Cache Data".

5. Finally, select "Restart the system immediately" and press "Power" or "Search" to confirm. After restarting the phone, you will find that the lock screen mode doesn't work! At this point, the phone password is unlocked.
