About multi-factor authentication


What is multi-factor authentication?

Multi-factor authentication (MFA) is a way of verifying users that requires more than one step to complete. Users can’t log in with just their username and password: an additional “factor” is required, such as a code sent via SMS or obtained from an Authenticator app. This ensures users are strongly authenticated and prevents bad actors from accessing an account even if they have acquired the username and password.

Authenticator app authentication

Authenticator apps are installed on your device and generate codes which are valid for a limited time and which can be entered as the additional factor. Examples of popular authenticator apps include Google Authenticator, Microsoft Authenticator and Authy (from Twilio).

Text message authentication

SMS can be used to send users a one-time code which they will then be prompted to enter before they can finish authenticating.

Passkey authentication

Passkeys are a replacement for passwords. A password is something that can be remembered and typed, and a passkey is a secret stored on your device, unlocked with a biometric sensor (such as a fingerprint or facial recognition), PIN, or pattern, freeing you from having to remember and manage passwords.
