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."

Go to the sign in page of the product (for Google Accounts it is myaccount.google.com). Enter your Gmail username (everything that appears before '@gmail.com'). Enter your password.

Type in your username and password. Once you've opened the web address of your email provider, you will see a login page. Enter your email account's credentials (username and password) in the text fields provided. If you forgot your password, you can usually click the "Forgot Password?" link to reset it.
