What should I do if I forget my phone unlock password?

If you use a vivo phone and forget the screen lock password:

Based on consumers' privacy and information security, the screen lock password needs to be set manually by consumers and stored locally in the mobile phone through encryption algorithm. The mobile phone has no function of automatically setting or modifying the password, and vivo/iQOO has no way to obtain the screen lock password. Once you forget the screen lock password, you will not be able to unlock the phone and retrieve the data in the phone.

If the wrong password is entered too many times in the lock screen interface, a reminder will be displayed on the screen to inform that the phone is locked. First of all, please think carefully, did you change your password yourself or did your friends and relatives change it? If you still can't unlock your phone after many attempts, please try the following methods.

1. Confirm whether to use multi-user (OriginOS 1.0/Ocean system is applicable).

In the screen lock interface, check whether the current user is a sub-user or a guest. Because the data between users is independent, the set password cannot be used. You can switch to the corresponding user and try to unlock it. Switching mode: click the user name and select the corresponding user.

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

Second, reset the phone through cloud services.

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 cloud service webpage through other devices, log in to the vivo account to enter the "find mobile phone" page, select "data backup", back up your data to the cloud service, and then select "empty your mobile phone". This operation will erase all data in the phone, including the password. If the function of "finding mobile phone" is not turned on, but the mobile phone can be unlocked by biometrics (fingerprint or face unlocking), you can interconnect the mobile phone and transfer the backup data of the computer version, then open the cloud service APP to start the function of "finding mobile phone", log in to the cloud service webpage, and enter the page of "finding mobile phone" to operate "clearing mobile phone".

* Note:

① Find the "data backup" of the mobile phone page. Only data that supports automatic synchronization, such as contacts, short messages, schedules, notes, etc., can be backed up to the cloud service, but photos and videos are not supported. Please confirm the data backup on the cloud service webpage after knowing the sending instructions. If photos and videos are not 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, it 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 webpage of the cloud service, such as data backup, emptying the mobile phone and so on.

Third, reset the phone through recovery mode.

Some models can use the 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 can't keep the data on your mobile phone, and once the data is cleared, it can't be recovered.

Step 1: Shut down.

Press and hold the power button until the power off slider or button appears on the screen, drag the slider or click the button to turn it off, and then wait for one minute to ensure that the phone is completely turned off.

Note: If the "lock screen, turn off and unlock" function of the mobile phone has been turned on before (Settings >; Security > screen lock and unlock), you need to enter the screen lock password to close it. At this time, you can press and hold the power button and the volume down button at the same time 10 seconds or more to forcibly restart the phone. When the phone restarts the black screen, follow the subsequent steps. You can also wait for the battery of the mobile phone to be turned off after use, and the charging state can be operated according to the following steps.

Step 2: Set the phone to recovery mode.

1. When the phone is turned off or restarted, press and hold the power button and the volume up button for 3~ 10 seconds at the same time before the screen lights up, and release the button until the word FASTBOOT is displayed on the screen.

2. Press the volume button to move the cursor to "Enter Recovery", and press the power button to confirm the entry until the word "Restore" appears on the screen. At this point, the phone has entered recovery mode.

Step 3: Clear data (only supported by some models)

1. Select "Clear Data" in the recovery mode interface, and then select "Clear All Data". At this time, the mobile phone data will be emptied. Please wait patiently for the liquidation to be completed.

2. When the words "Clear Successfully" are displayed on the screen, select "Return" to return to the recovery mode interface, and then select "Restart" to set up and use the mobile phone.

* Note: If you enter the activation interface (display: activate the device) after the mobile phone is reset and restored, it is because the mobile phone has turned on the "find mobile phone" function, and you can enter the system by entering the correct password of vivo account. If you forget the password of your vivo account, you can click on the webpage link here to try to reset the password.

Fourth, go to the service center.

If you still can't unlock the phone by the above methods, please bring the purchase voucher and the webpage link of the phone to the vivo customer service center to unlock it. After the service center swipes the card to unlock it, all the data in the mobile phone will not be retained.

Tips: It is suggested to call the staff of the service center in advance when going to ensure that the staff will go again during normal working hours, avoid running empty and pay attention to safety on the way back and forth.
