When off-the-shelf products are just not flexible enough

IdentityServer gives you full control over your UI, UX, business logic, and data.

In IdentityServer, customizing your workflows is not an afterthought. Our APIs and extensibility points allow adapting to your workflows and business rules without having to find complicated workarounds.

You can choose whichever UI framework or technology suits you best to integrate with our token engine.

We believe that C# is the best DSL — don't bother with trying to express your logic in YAML, XML, or other "languages".

In short, if what you want to achieve is doable in .NET Core, it is doable with IdentityServer.

We are trueto standards

There's a reason why protocols exist: they ensure interoperability, a common language, and proven security practices.

Being fully standards compliant is very important to us, and we want to give you access to every aspect of the OAuth and OpenID Connect protocol family.

IdentityServer is officially certified by the OpenID Foundation, and our ongoing mission is to implement every published specification from the IETF working group.

Unlimited hosting options

You are not forced onto a specific hosting environment or other peoples' servers — you are not forced to use a specific database or geographical region.

You can run IdentityServer wherever you need: on premises, cloud, behind a VPN, Windows, Linux, Docker, Kubernetes — you name it. Even in a suitcase.

Putting your requirements in the center is our motivation.
