vivo mobile phone does not have a master password. If you forget the screen lock password, you can refer to the following methods:

If you forget the screen lock password, please refer to the following methods:

Based on the privacy and information security of consumers, the screen lock password needs to be manually set and confirmed by consumers and stored in the local mobile phone through encryption algorithm. The mobile phone does not have the function of automatically setting or modifying the password, and vivo/iQOO does not have the way to obtain the screen lock password.

if you enter the wrong password too many times in the lock screen interface, a reminder will be displayed on the screen, informing you that the phone is locked. First of all, please carefully recall whether you have changed your password by yourself or by friends and relatives. If you still can't unlock your phone after repeated attempts, please try the following methods.

1. Confirm whether to use multi-users (OriginOS 1./Ocean system is applicable)

Check whether the current users or visitors are in the lock screen. Because the data between users are independent, the set password cannot be used. You can switch to the corresponding user and try to unlock it. Switching method: click the user name and select the corresponding user.

* Note: If the user name is not displayed in the screen lock interface, it means that the mobile phone is not enabled for sub-users or visitors.

2. Reset the mobile phone through the cloud service

If you have turned on the "find mobile phone" function on your mobile phone before you forget your password, you can try to access the webpage link of the cloud service webpage through other devices, log in to the vivo account and enter the "find mobile phone" page, select "data backup", back up the data to the cloud service, and then select "clear mobile phone". This operation will erase all data in the phone, including the password. If the "find mobile phone" function is not turned on, but the mobile phone can be unlocked (fingerprint or face unlocked) by biometrics at present, you can connect the mobile phone to the computer version of the webpage link to back up data, then open the cloud service APP to turn on the "find mobile phone" function, log in to the cloud service webpage, and enter the "find mobile phone" page to operate "clear the mobile phone".

* Note:

① Searching for "data backup" of mobile phone pages can only back up data that supports automatic synchronization, such as contacts, short messages, schedules, notes, etc., to the cloud service, and does not support backing up photos and videos. Please confirm the data backup on the cloud service webpage after sending instructions. If photos and videos have not been backed up in the cloud service, the data of photos and videos will be lost when the mobile phone is cleared.

② if the words "to protect data security, all functions can be used only after unlocking" are displayed on the screen, which means that some functions of the mobile phone have been disabled. In this scenario, the mobile phone will not execute the related instructions sent by the web page of the cloud service, such as data backup, clearing the mobile phone and other instructions.

third, reset the phone through Recovery mode

some models can use Recovery mode to reset the phone, which will erase all the data in the phone, including the password. If you backed up your phone data before you forgot your password, you can restore the relevant data after resetting your phone. If you haven't backed up the data, you won't be able to keep the data on your mobile phone, and once the data is cleared, it won't be recoverable.
