Occasionally Google Gmail user may want to reset the password which used to login into the Gmail account via web, POP3 and IMAP as the original password has been forgotten, or misplaced. Gmail credentials integrates and bases on Google Account. So changing the password for Gmail will also change the password for the associated Google Account.
In order to reset and change the password of Gmail and corresponding Google Account with the affected Gmail email address, follow these steps:
If you're unable to answer your security question and the account has a secondary email address configured, a link will appear at the bottom of the secret question results page. Clicking on the link will has a password reset email message sent to the secondary email mailbox. After receiving the email, follow the link to reset the password.
If you have login to Gmail in the preceding 24 hours period, the password reset email will be sent immediately instead. Follow the link to reset the password. If you don't have a secondary email address, or if you no longer have access to that account, repeat the steps above after 5 days. At that point, you'll be able to reset your password by answering the security question you provided when you created your account.
