Help when you need it

Use another device to sign in

Quick Connect lets an already signed-in phone or computer approve the device you’re setting up. Use it when your app shows a Quick Connect code.

  1. Keep the code visible on the new device.
  2. On a phone or computer, open Blackbeard’s Vault Jellyfin and sign in to the same Jellyfin account. Match your username’s capital and lowercase letters exactly.
  3. Open your user/profile menu, choose Quick Connect, enter the new device’s code, and confirm.

If Quick Connect is unavailable, use password sign-in on the new device. A local app PIN is a different optional setting.

Something not working?
  • Can’t connect? Check the s in https:// and copy the full server address again. Don’t add a port number.
  • Can’t sign in? Match every capital and lowercase letter in your username. Use your Jellyfin account, not your email or an Emby login. Remove accidental spaces.
  • Video or sound problem? Close and reopen the app, check for an update, and try another title.

Still stuck? Message @Captain Cruv on Discord. Include your device, the app name, and a picture or the exact wording of the error. Never send your password.

Moonfin unavailable or not working?
