Two-step authentication offers an extra layer of security to your traditional single username and password verification process. It is designed to prevent someone else from accessing your account, even if they know your password.
For example, we already regularly use two-factor authentication when we swipe our credit card and are asked to enter a PIN for the transaction to go through.
In the new world of shared information, integrated applications and open source platforms, it is important to consider the safety of your information.
Xero recently introduced two-step authentication for users to access the online accounting platform.
