Make sure that your computer or laptop is on and that your operating system has fully loaded. Find your internet browser icon and click on it. In the top of the internet browser make sure to put in mail.google.com. This will take you to the main page for Gmail. Once you are on the main page you will have to Sign-In.
Click on the “I can’t access my account” Link. You will be taken to a new screen.
Google will ask you to type in your full email address or your Gmail username. In case you can’t remember your username, you can click on “Forgot your username” link to find out. It is best to keep this type of information written down somewhere so that if you forget it you can always check your sheet for all the information. It is important to keep that sheet with all your usernames and passwords in a safe place somewhere near your computer or laptop. Also, if you can remember the other email account that you originally linked with your Gmail account then search in that account and look for an old email which was probably sent by Gmail to let you know what your username is.
You will be asked to retype the captcha code for security purposes. Hit the continue button to move to the next process.
You will be asked to verify your identity by Google. You can confirm that it is indeed your own account by either correctly answering your security question or receiving a reset password in your secondary email. Try to remember your security question as this is another good thing to keep written down somewhere safe.
You can now use your new password after everything provided has been verified.
You can now login to your Gmail account with your new password. Make sure that you note down this new password or save the confirmation email from Gmail with all your account details.
