Two-Factor Authentication for Visa Consultant Logins

What does two-factor authentication actually secure?

Two-factor authentication decides whether a login attempt is genuinely who it claims to be, before that login is ever allowed to succeed. A password on its own — typed into a login form, correct or not — has always been a single point of failure: it can be guessed, reused from another account, phished through a convincing email, or simply written down somewhere it shouldn't be. VisaBOS can require a second step after the password — a one-time passcode (OTP) generated specifically for that login attempt — before access to any case, document, or report is granted. This is a different layer from role-based access control, and the two are easy to confuse if you haven't worked with both. Role-based access control is about authorization: once someone is already logged in and verified, what are they allowed to see or edit. Two-factor authentication is about authentication: proving, before any of that matters, that the login is actually them. A consultancy can have very carefully scoped roles and still be exposed if a single leaked password is enough to log in with nothing else required — which is exactly the gap this feature is built to close. An admin can also choose which roles or branches must use two-factor authentication, see login activity across the team, and rely on automatic account lockout to blunt repeated password-guessing attempts.

Two-factor authentication verifies who is logging in; it does not decide what they can see once inside. That's the job of our role-based access control feature, and once someone is logged in, our case audit trail and compliance logging feature records what they actually did — together, the three give a consultancy verified logins, scoped access, and an accountability record, rather than any single layer trying to do all three jobs at once.
