Forgetting the password to your Gmail
account can be a huge inconvenience, especially when your account is at the center of many of your online activities. However, it is possible to recover your password.
Recovering your Gmail password
is fairly easy and straightforward. If you have forgotten your password and can no longer access your Gmail account, here are a few quick steps to get your account back.
Gmail Account Recovery
Go to Google's Account Recovery
page, enter your account information, and click Next
If you've previously linked a phone number to your account, you can use it to retrieve a verification code by SMS. Otherwise, you can click Verify your identity
and answer the security questions.
If you haven't accessed your account for 9 months or more, Gmail may have considered your account as abandoned and may have deleted it from the server. In this case, account recovery is no longer possible.
