Two-Factor-Authentication

If you use Google's email service Gmail, then you will need to take special care of the security of your account. If we say that even if the hacker has your Gmail password, the data cannot be stolen, then you would also like to know about this. Actually, Google provides the facility of two-factor-authentication for account security. With this setting enabled, the security of your Gmail account is ensured.

Two-factor authentication works as an extra layer for the security of your Google account. As soon as you try to log in to a Gmail account from a new device, after entering the password, there is a need to come to the second step. It will be confirmed by Google that the Google account is being used by the real user only. When the setting is on, a Google prompt will appear on your primary phone. Gmail will open in the second device only when the authentication is passed by you from the primary device.

Keep in mind, two-factor authentication works differently for trusted devices. Once the two-step verification is passed in a new device, the next time you can log in to Gmail with the password on this device.
This feature is useful in protecting your account from hackers. If a hacker hacks the password of your Gmail account, then he will have to come to the second step for login. Which will be based on your permission. Unless you give permission, the account cannot be logged in even with the password.
