Multi-factor authentication (MFA) is becoming the world standard. Secure your users and your applications by requiring more than just a password at login.
The right form of MFA depends on your audience and your application. FusionAuth supports methods like email, SMS and TOTP (used by applications like Google Authenticator). Enable one or many, depending on your needs. You can also control how long before users are re-prompted for their MFA method.
Users can set up MFA on their own using customizable profile management pages, including recovery codes. Or integrate with our APIs to embed MFA setup into your application.

Let users have as many different MFA methods as they want, including multiple email addresses, phone numbers, and authenticator apps. This reduces MFA device loss anxiety and increases ease of use for your users, while increasing account security by not tying MFA addresses with login identifiers.
Sometimes you want to be extra sure before taking a dangerous action, like sending money or deleting an account. Trigger an MFA request within your application using our APIs or SDKs.
Configure MFA rules on an application by application basis, allowing for targeted MFA prompts. Some apps require MFA to provide additional app security, others accept a tradeoff to reduce login friction. You’re in control.
FusionAuth is built from the ground up to be localized, including MFA messages. Support your global audience by delivering messages in their preferred language.
