If you use Gmail, check the inbox of the recovery email address you provided when you signed up for Gmail. If you didn't provide a recovery email address, you can try another way to recover your account. You'll be asked some questions to confirm it's your account. Answer as best you can.

To find all your Gmail accounts or Google accounts, you can follow these steps: Open a web browser and go to the Google Account Recovery page (https://accounts.google.com/signin/recovery). On the account recovery page, enter the email address or phone number associated with your Google accounts and click "Next."

On your computer, go to Gmail. Enter your Google Account email or phone number and password. If information is already filled in and you have to sign in to a different account, click Use another account. If you get a page that describes Gmail instead of the sign-in page, at the top right of the page, click Sign in.
