Two-factor Authentication (2FA) is an extra layer of security to protect critical information, like your online accounts. Every time you log into an account with a password and receive a verification code via email to verify your identity, you are using 2FA. It means that, in addition to your password, you need a second credential to confirm your identity before logging in.
When users attempt to log into an account that uses 2FA, they first enter their username and password as usual. The system then generates a one-time code and sends it to the user’s email. The user then enters the code in addition to their password to confirm their identity and gain access to the account.
This process makes it much more difficult for an unauthorized person to access the account, as they need both the password and the second factor. Using 2FA, organizations and individuals can increase the security of their sensitive information and help prevent data breaches and hacking attempts.
Overall, 2FA provides a simple and effective way to increase the security of online accounts and sensitive information.
