Two-factor authentication (2FA) is a security feature that adds an extra layer of protection to online accounts. With 2FA enabled, users must provide two forms of identification to access their accounts, typically a password and a unique code sent to their phone or generated by an authentication app. <\/p>\n\n\n\n
This significantly reduces the risk of unauthorised access to accounts, as an attacker would need both the password and the second form of identification to gain entry. Many websites and apps now offer 2FA as an option to their users, and it is generally recommended to use it wherever possible to enhance account security. <\/p>\n\n\n\n
