How can I prevent someone from resetting the password using my phone number if my phone is lost?

Touch Settings > Log in to HUAWEI ID and log in. On the displayed screen, touch Security option, and set Email only as the method to reset the password and verify the identity. The setting can help prevent your password from being reset by others using the phone number if your phone is lost. Before the setting, you need to associate your HUAWEI ID with a valid email address or a security email address.
