You get every feature and acronym you need: registration & login, passwordless, SSO, MFA, SAML, OIDC, OAuth, JWT, social login and more. Comply with GDPR, HIPAA, COPPA, and PCI requirements in seconds.
FusionAuth installs on any platform, any computer, anywhere. Host it yourself or use FusionAuth Cloud, our fully managed SaaS hosting service.
Download FusionAuth and get started - no plans, registration, or credit card required.
GET STARTEDFusionAuth gives you all the features of SaaS platforms plus true data isolation, the ability to deploy anywhere, transparent & scale-friendly pricing, and awesome-sauce support.
Secure identity is massively complex. A talented dev COULD do it all, but it takes months to build, test, and maintain. Use our one-minute install and spend your resources on something that makes you money.
With FusionAuth you get every feature with one easy install–no additional modules or configuration scripts to muck with. Plus, FusionAuth is built on modern technology, simple to deploy, and scalable to hundreds of millions of users. Just download, deploy, and integrate with our RESTful APIs. Simple.
