Huawei's mobile phone account number and password have been forgotten, and the mobile phone number has been changed. What should I do?

If you forget the password, you can unlock the Android phone through the previously set secret protection question or the backup password. If you still can't unlock it, you can solve it in the following ways:

1, contact the terminal manufacturer or customer service to help unlock it;

2. If you have experience in brushing before, you can also try to clear the previously set screen lock password through third-party brushing software (brushing wizard, etc.). ). However, brushing the machine is risky, so it is recommended to contact the customer service of the manufacturer to avoid unnecessary losses.
