There are a few ways to bypass a TCL phone’s password, depending on the model of phone.
One way is to enter the wrong password multiple times until the phone prompts you for your Google account information. If you know your Google account information, you can use that to unlock your phone.
Another way is to factory reset the phone, but this will delete all of your data.
Finally, if you have a TCL ID account, you can use that to log in and unlock your phone.
