What if the headline account can't remember the mobile phone number?

You can log in as a tourist without information authentication, but if you want to do something important on it, if you can't find your mobile phone number, you can only change your account, because important things need a mobile phone verification code to log in to the headlines, which is convenient to protect your privacy and make you safer to use. So if the previous mobile phone number can't be used, I suggest you log in with your current mobile phone number.
