Go to http://accounts.google.com/signin/usernamerecovery and enter any email accounts or phone numbers that you've had for a while and which may have been used as recovery info. The “find your email” page can help you locate any forgotten Google accounts.

After you select Forgot password and enter your username, we offer you recovery options in order to access your account. If you can't access these recovery options, you can click the link at the bottom of the page to verify your identity. You'll then be given a series of questions to verify that you own the account.

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.

A Google Account gives you Google-wide access to most Google products, such as Google Ads, Gmail, and YouTube, using the same username and password.
