^{Originally posted by tyler-jewell September 15, 2022} While publishing to firebase hosting using the FIREBASE_TOKEN environment variable, I got this warning:

Authenticating with --token is deprecated and will be removed in a future major version of firebase-tools. Instead, use a service account key with GOOGLE_APPLICATION_CREDENTIALS: https://cloud.google.com/docs/authentication/getting-started

Can we update the documentation to reflect this?

As Firebase docs still mention --token in their docs for authentication, I'll leave it as is.

Both methods (Authenticating via service account and Authenticating via token) are in the documentation. There is also a warning note in the docs to say that using a token will be deprecated at some point in the future.
