If you've forgotten your Google Account password, you can try to recover it through the Google website. On your phone or computer web browser, go to www.google.com/accounts/recovery. Follow the instructions on the screen to reset your password.

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.

Simply open your browser. And type the person's name + email address. You can also try the following queries: “Firstname lastname” + “@gmail.com”
