beaconauth
by Summpot
BeaconAuth adds a web-based OAuth passkey sign-in layer to Minecraft servers, and the server owner hosts the BeaconAuth service that handles it.
What it does
A server owner runs the BeaconAuth web service on their own infrastructure and points the server at its URL. During login, the mod opens the configured BeaconAuth page in the player's browser, where the player completes sign-in with an OAuth passkey. A temporary local callback listener receives the result once the flow finishes.
Once login completes, the result is passed back to the server with a signature that is checked with JWT and JWKS against the keys of the configured BeaconAuth server. Server-side authentication behavior can be configured, and client messages are localized.
The mod is released for Fabric, Forge and NeoForge across the game versions 1.19.2, 1.20.1, 1.21.1 and 1.21.8, under the MIT License, and is open source. Public links for the source code, issue tracker and wiki are available. Files are marked beta.
Key features
Passkey sign-in
Players authenticate with an OAuth passkey through a web login page hosted by the BeaconAuth server.
Signed session verification
The server checks each authentication result against the configured BeaconAuth keys using JWT and JWKS.
Configurable server behavior
Server owners set their own BeaconAuth server URL and control how authentication is enforced on the server side.
Compatibility
Latest build for each game version and loader.

Use cases
Community-managed accounts
A server community can keep its own account verification under its control instead of relying on a third-party login service.
Who it’s for: Server owners who want web-based passkey login for their Minecraft community, and who are prepared to host a BeaconAuth web service themselves.
How it compares
OAuth Account Manager is client-side only, open source under the Apache License 2.0 and published for 1.21.1, so it changes nothing on the server. Nedologin runs on client and server and is published for 1.19.2 – 1.21.11 under a custom license that is not open source. authlogic runs on client and server, is open source under the MIT License and covers 1.20.1 – 1.21.11. IDELogin is client-side only, open source under the MIT License and covers 1.20 – 26.2.
