When your device can still be unlocked into the desktop through fingerprints or faces, please back up the data on the device first.
Step 1: Confirm whether the password has been changed.
I suggest you think carefully about whether you have changed your password recently, or whether anyone who has been in contact with the device, such as family members or others, has changed your password.
Step 2: Confirm whether to use multi-user mode.
I suggest you check whether the user name or visitor is displayed in the lock screen interface. If it is displayed, it means that your device has turned on multi-user mode, and you can switch users to try to unlock it.
Step 3: Force the factory settings to be restored.
If the above operation still fails to solve the problem, it is recommended that you forcibly restore the factory settings of the equipment.
? This operation will erase all data from the device and cannot be recovered. It is recommended to back up the data before operation.

Step 4: Go to the customer service center.
If the above methods fail to help the recovery, it needs to be detected and handled by the customer service center (customer service center address: go to vivo official website /vivo Mall APP—- My-service outlets/after-sales outlets-select provinces and cities to inquire about the customer service center address). It is suggested to call the customer service center in advance to confirm the relevant matters and know that the office hours are coming soon, so as not to delay precious time.
Tips:
1, some early models can reset the screen lock password through secret protection. When you enter the wrong password five times or more, click the "Forgotten Password" option on the screen to verify the answer to the secret security question, and then you can reset the password.
2. In order to protect personal data more effectively and avoid unexpected situations. It is recommended that you back up the equipment data in a timely and planned manner when using the equipment in the future. On the device, you can go to Settings > Account > Cloud Service and use the functions of "Cloud Backup" or "Data Synchronization" to back up the device data to the cloud. When restoring cloud data, you can click the "Restore Backup Data" area at the bottom of the "Cloud Backup" page to restore cloud data to the current device conveniently.
