Creating layers of security that criminals won’t break
Multi-Factor Authentication makes it extremely difficult for a cybercriminal to hack into your accounts, even if they know your password.
Multi-factor authentication is a process where a user is prompted during the sign-in process for an additional form of identification, such as entering a code on their cellphone or providing a fingerprint scan.
If you only use a password to authenticate a user, it leaves an insecure vector for attack. If the password is weak or has been exposed elsewhere, is it really the user signing in with the username and password, or is it an attacker? When you require a second form of authentication, security is increased as this additional factor isn’t easy for an attacker to obtain or duplicate.
