Need help with 2-step verification

Sign in

To open Gmail, you can login from a computer, or add your account to the Gmail app on your phone or tablet. Once you're signed in, check your mail by opening your inbox.

1. On your computer, go to gmail.com.
2. Enter your Google Account email and password.
3. If information is already filled in and you need to sign in to a different account, click Use another account.
4. If you see a page describing Gmail instead of the sign-in page, click Sign in in the top right corner of the page
