Passwords or passwordless, single sign on or multi-factor, FusionAuth lets you authenticate in every way, with standards based authentication using Oauth2, OIDC, or SAML v2.
FusionAuth gives you quick and easy authentication for any type of application at all, including web, mobile, desktop and console apps. Use FusionAuth's OAuth2, OpenID Connect or SAML v2 front-ends, or build your own login experience. We love developers, so if you build your own, our library of content is here to help you along the way.
Don’t rely on passwords to protect users’ accounts. FusionAuth lets users authenticate in several easy, secure ways: single sign on, multi-factor authorization (we let you use a number of authorization styles) and passwordless. Take the guesswork and stress out of sign-on by sending magic links to your users, adding biometric authentication, or by using one sign-in to offer users access to all your applications.
