Obligator is a pre-release beta software designed for self-hosters who need a specific combination of features not found in other open source OpenID Connect (OIDC) servers. It is simple to deploy and manage, supports anonymous OAuth2 clients, allows authentication to multiple domains at once, enables passwordless email login, and can be configured at runtime using an API. The philosophy behind obligator is that identities are built on email, and it aims to validate user control over an email address as simply as possible. While the software has not undergone a security review, testing and feedback, especially regarding security, is appreciated. It can be run using Docker or downloaded as a static executable.
Please note that this is pre-release beta software and has not yet undergone a security review.
