Basic info about two-factor authentication (2FA)

Two-factor authentication (2FA) is a security measure used to add an extra layer of protection to online accounts beyond just a password. 2FA requires users to provide an additional form of identification, or “factor,” to access their accounts. The idea behind 2FA is that even if someone knows your password, they would still need to provide this additional factor to gain access to your account.

There are several types of factors that can be used for 2FA, including something you know (like a password or PIN), something you have (like a phone or security token), or something you are (like a biometric identifier such as a fingerprint or facial recognition). 2FA can be used for a variety of online accounts, including email, social media, and banking accounts. Many online services now offer 2FA as an option to help protect their users’ accounts. The most common implementation of 2FA involves sending a code to your mobile phone via SMS or a mobile app, which you must enter after providing your password. Other methods of 2FA include using a physical security key or using biometric identifiers like fingerprint or facial recognition.

Overall, 2FA is an important security measure that can help protect your personal and sensitive information from unauthorized access, theft, and hacking.

Why need active two-factor authentication (2FA)

ou should activate two-factor authentication (2FA) on your Gmail account to provide an additional layer of security beyond just your password. With 2FA, you will need to provide a second factor of authentication in addition to your password to access your account. This second factor could be a code sent to your phone, a biometric scan like your fingerprint, or a security key that you have physically in your possession.

By enabling 2FA, you make it much harder for hackers or unauthorized persons to access your Gmail account, even if they have obtained or guessed your password. Even if someone else gains access to your password, they will not be able to access your account without the additional factor of authentication.

2FA is an important security measure for any online account that contains sensitive information, and it can help protect your personal and private information from unauthorized access or theft.
