What is Two-Factor Authentication?
Two-factor authentication (2FA) sounds complex but it’s not, it’s just a way of 'double-checking' that you’re really the person you’re claiming to be when you log into your online accounts, such as banking, email or social media.
2FA means using a combination of two of the following:
- Something you know (e.g. a password),
- Something you have (e.g. a phone for SMS),
- Something you are (e.g. your voice, thumb print, face scan).
Why is it important?
2FA makes it harder for someone else to access your online accounts. For example, even if a cybercriminal guessed or stole your password they wouldn’t be able to perform an online transaction without your 2nd factor.
