BYO Auth allows you to add advanced authentication features like session management, SSO, and passwordless login to your existing system without migration. It's designed to integrate seamlessly with your current infrastructure, whether it's built in-house or third-party. The self-hosted option gives you complete control over user data.

Pocket ID is a straightforward OIDC provider that enables authentication using passkeys instead of passwords, positioning itself as a simpler alternative to more complex self-hosted providers like Keycloak and ORY Hydra. It supports various setup methods, with Docker being the easiest, and encourages contributions from the community.
