Go to your Google Account. On the left navigation panel, select Security . On the Your devices panel, select Manage all devices. You'll see devices where you're currently signed in to your Google Account or have been in the last few weeks.

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.

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.
