Zitadel

Zitadel is a tool that manages who can log into your application and what they can do once inside. You can set it up to handle user accounts, control access to different features, and keep track of security events. Unlike building your own login system, Zitadel provides everything ready to use.

It supports modern login methods like social accounts (Google, Facebook), company systems (Microsoft, Okta), and passwordless options using fingerprints or face recognition. The platform uses standard protocols that work with any application, so your app simply talks to Zitadel without needing custom code for each login method.

There is a free tier that works for small projects, and paid plans that add more users, better support, and advanced features for growing businesses.
