Where it fits

Authentication · Open-source serviceAn open-source identity server with organizations (multi-tenancy), passkeys and SSO built in, as a hosted cloud or on your own servers.Trade-off: AGPL license for self-hosting; a full identity server is more to run and learn than an auth library in your app.
