Procedure on how to setup Firebase for CI and headless servers is described here: https://github.com/firebase/firebase-tools#using-with-ci-systems

The Firebase CLI requires a browser to complete authentication, but is fully compatible with CI and other headless environments.

1. On a machine with a browser, install the Firebase CLI.
2. Run firebase login:ci to log in and print out a new refresh token (the current CLI session will not be affected).
3. Store the output token in a secure but accessible way in your CI system.

There are two ways to use this token when running Firebase commands:

1. Store the token as the environment variable FIREBASE_TOKEN and it will be automatically used.
2. Run all commands with --token flag in your CI system.
