    Pocket ID

    Pocket ID

    Easy-to-use OIDC provider that allows to authenticate with passkeys

    Pocket-ID is an open-source OpenID Connect (OIDC) identity provider that prioritizes passwordless authentication using modern passkeys, making secure login easier for self-hosted services. By supporting passkeys instead of traditional passwords, Pocket-ID aligns with evolving web authentication standards, letting users sign in with devices, hardware keys like YubiKey, or platform-managed credentials. It’s designed to be simpler to install and use than larger identity solutions like Keycloak or Hydra and integrates smoothly with other self-hosted applications that understand OIDC protocols. With Docker-ready setup and broad community interest, the project supports a fully self-managed authentication stack where you control user identity, sessions, and login flows without relying on third-party services. It has gained popularity in the self-hosted ecosystem as a straightforward way to add single sign-on capabilities and modern security to your apps.

    OpenAuth

    OpenAuth

    Universal, standards-based auth provider

    OpenAuth is an authentication system aimed at modern serverless and edge runtimes, providing a cohesive way to add sign-in flows and session management to web apps. It supports common patterns such as OAuth with popular identity providers, email-based links or codes, and passkeys/passwordless options, while exposing a simple API that fits full-stack frameworks. The project is designed to be infrastructure-friendly, aligning with managed stores and serverless platforms so sessions, webhooks, and callbacks work reliably at scale. It emphasizes secure defaults, including robust token handling, CSRF protections, and clear session lifecycles, while leaving room for customization where apps need it. Developers can bring their own database or storage layer and wire it through adapters without rewriting core logic. The goal is to remove boilerplate around sign-up/sign-in, user profiles, and authorization checks so teams can ship features faster.
