Activate two-step verification on Gmail, Why and how?

Enable two-step verification on Gmail

Google recently announced the change in the connection method. This is the addition of a second verification step, after entering the mot de passe, aimed at strengthening account security. Two-step verification on Gmail will be automatically activated from November 09, 2021 and will be mandatory on many accounts.

Why a second validation step?

The objective here is the protection of your personal data by strengthening the security of your account. By using more than one login step, you will reduce the risk of your account being hacked and your information from being stolen and exploited by hackers.

Thus, for any malicious person, the theft of your mot de passe will not guarantee access to your account. Except in case of access to your phone, in addition to having your password. To log in, you will need to have your phone with you. One more reason to always lock your phone.

After entering the password, you will be asked to pass a second verification on your phone. Each time you log in on a new device, Google will send a notification (login prompt) to your phone, which you will be asked to confirm.

This is how the Google sign-in prompt appears on my smartphone after enabling two-step verification and trying to sign in on a new computer.

When you enter your password, Google prompts will be sent to all phones you're signed in to. All you have to do is press the notification to read it and confirm the connection or reject it.

You may also receive a verification code by SMS. Receiving it will depend on your carrier's coverage and may involve costs (rarely). This is one of the two-step verification methods on Gmail. However, make sure that you are the only one with access to your SMS.

Check Gmail Account Recovery Info

To verify your identity at the time of connection or in the event of suspicious activity on your account, Google may use one of the following three methods:sending the verification code to your phone number, on your recovery email address orsending connection notifications to your private phone.

This is why before activating XNUMX-step verification on Gmail, it is recommended to confirm the account recovery information. Google may use either of these to help you sign in if you're having trouble signing in.
