Xero Multi-factor authentication for security
Multi-factor authentication (MFA) adds an additional way of checking that it’s really you when you log in to Xero. It combines something you know (your user name and password) with something you have (an authentication app on your smartphone or tablet). This second layer of security is designed to prevent anyone but you from accessing your account even if they know your password. So if you don't always have your phone on you this is a great solution.
