2 Factor Authentication (2FA) is an extra layer of security that is often used to protect sensitive information. When enabled, a user must provide two pieces of evidence (or ‘factors’) to gain access to a service or website. This could include something you know (like a password or PIN), something you have (like a physical token or smartphone) or something you are (like a biometric scan). 2FA is very effective at preventing unauthorized access to accounts and is considered to be much more secure than using a single password alone.
