What is two-factor authentication?


Two-factor authentication, also known as multi-factor authentication, is used as an additional layer of protection to ensure the security of online accounts in addition to usernames and passwords.

A two-factor authentication process usually involves sending a one-time pin to a user via an SMS or email. The member must fill in their one-time pin when prompted to, on a website or mobile app, to verify that they are the person accessing their account.

Both Qatar Airways Privilege Club and British Airways Executive Club make use of two-factor authentication to protect their members’ accounts and members may be asked to complete both Privilege Club and British Airways two-factor authentication measures when linking their accounts, moving or spending Avios.
