It is the process that starts by default: Google asks you to enter a 'password' that you remember. In itself, it does not offer any solution since unless you write the current password (and that, in theory, you do not remember), it will not let you pass.
Click on 'Try another way' and choose another option to recover the account.
If you registered the Gmail account on another mobile, tablet, or computer, a notification from Google would have appeared on the screen. Write the characters that appear on the phone screen where you are trying to recover the password, and Google will let you pass. Otherwise, you will have to use another method.
