Is your Gmail account stopped working? Before going to the solution let me first tell you its possible causes. If you Gmail account suddenly stops working then it means either,
• You have forgotten your Username, Or
• Password;
If you know your username then basically there are two methods of password recovery. The first one of through registered mobile number and the second one is through registered email ID.
Gmail Password Recovery through Registered Mobile Number
If you have access of your registered mobile number then make request of verification code to be received on your number. Thereafter, you need to enter the same at the requisite place. Once your account is the verified by Google then you will be allowed to change your account password.
Gmail Password Recovery through Registered Email ID
In case you do not have access of your registered mobile number then you may choose the option “password recovery through registered email ID”. Once you selected this option, then you’ll get a link to change your password at your registered email ID. Just follow that link and create a new password for your account. In future, if you face the similar situation then you need to follow the follow the same procedure what I prescribed over here.
