When you forget your phone password, there are a few possible ways to unlock your phone. Here are three common methods:
Unlock with a Google account(for Android devices):
Prerequisite: Your phone has been set up and logged in to your Google account, and the account password is known, and your phone can be connected to the Internet.
Steps: Enter the wrong password 5 times in a row, and you will be prompted with "Forgot Password" or a similar option. Tap on that option and enter your Google account and password to unlock your phone.
Clear the data to unlock
Prerequisite: For users who don't have important information.
Steps: In the shutdown state, press and hold the volume up button and the power on button at the same time to enter recovery mode. Select "Wipe Data" or a similar option and restart your phone. Note that this will delete all user data, but the application will usually be retained.
Use a cloud service to wipe out your password
Prerequisite: You have a cloud service account associated with your phone, such as an Apple ID (for iPhone) or a corresponding brand account (for other phone brands).
Steps: Log in to your cloud service account, find "Devices" or a similar option in the settings, select your phone, and remotely wipe your phone data or change your password.
Please note that it is important to back up your data before performing any unlocking operations as the above methods may result in data loss. If the above methods are not applicable or feasible, it is recommended that you consult the official guide of your mobile phone brand or contact customer service for more specific help.
