European authentication providers

Add login and identity management to your app without relying on US identity providers.

Authentication tools handle logins and user accounts for your app. They sit on top of your users' passwords and identities. A European provider keeps that under EU law. Ory and ZITADEL are both open-source, so you can host them yourself. ZITADEL comes from Switzerland and Ory from Germany. Your users' identities stay in European hands.
