If you're trying to find a gmail account by name and password, you can use a gmail account search tool to help you locate it. Simply enter the person's name and any other identifying information you have, and the tool will search through google's database to find any matching accounts.

To get started, head to g.co/recover and enter your Gmail address. If possible, try the following to make recovery easier: Use a computer, phone, or tablet you've previously used to sign into your account. Use the same browser that you usually do, like Chrome or Safari.

To sign in to your Google Account (or any Google product): 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.
