First of all, please think carefully about whether you have changed your password, or whether you have been changed by relatives and friends. If you can't unlock it after many attempts, please try the following methods.
Case 1: Forget the screen lock password, but you can use your fingerprint or face to enter the desktop:
1. After backing up the data, please connect to the network, enter the cloud service-login account-find device-open "find device", open the webpage of vivo cloud service with other devices-enter the password of vivo account-find device-clear device-click "OK" to reset and clear all data, thus clearing the screen lock password.
Case 2: Forgot the screen lock password, unable to enter the desktop:
1. If you enter the wrong password multiple times, there is no "Forgot Password" option:
(1) Turn off the machine, and press and hold the volume plus button and the power button for about 5 seconds before turning it on. Press the volume button to select Restore, press the power button to confirm, and click "Clear Data" to clear the screen lock password. If the "find device" function is turned on, you need to verify the password of vivo account after restarting. The folding screen mode needs to be operated in the unfolded state.
(2) If the function of finding devices has been turned on, you can try to use other devices to open the webpage of vivo cloud service-enter the password of vivo account-find devices-clear devices-click "OK" to reset and clear all data, so as to clear the screen lock password.
2. If you enter the wrong password many times, there is a "Forgot Password" option:
In the password input interface, the screen lock password is entered incorrectly for five consecutive times, and the screen has the option of "Forgot Password". Click "Forgot Password" to fill in the previously set secret answer for verification and modify the screen lock password; If you forget the answers to the questions about screen locking and security protection, and the function of finding devices has been turned on before, you can try to clear the data and reset the password in the cloud service.
Note: If the search device is turned on and the network is stable, you can go to the vivo cloud service webpage-search device for "data backup" (only contacts, schedules, atomic notes/notes and other data can be backed up, but pictures and videos are not supported);
Note: After the model supporting FBE encryption technology is restarted, it will not be unlocked to enter the desktop, and the data cannot be cleared through cloud service instructions.
Situation 3: If you can't reset the screen lock password by clearing all the data, please bring the equipment, ID card and purchase voucher to the vivo customer service center for processing.
Note: "Clear all data" will restore the mobile phone to its initial state and delete all data in the system space of the mobile phone, including account number, system and application data and settings, and installed applications. Please back up the important data on your mobile phone before operation.
