I am writing an application in which I would like to use Firebase for the authentication of any sort of back end calls. Is there a way for me to get a token through a CLI or curl for local testing without having to spin up a front end to get the token?

You can refresh a Firebase ID token by issuing an HTTP POST request to the securetoken.googleapis.com endpoint. The refresh token's grant type, always "refresh_token". A Firebase Auth refresh token. The number of seconds in which the ID token expires.
To achieve this, you must create a server endpoint that accepts sign-in credentials—such as a username and password—and, if the credentials are valid, returns a custom JWT. The custom JWT returned from your server can then be used by a client device to authenticate with Firebase (iOS+, Android, web).
Once you have a service account key file, you can use one of the Google API client libraries to generate a Google OAuth2 access token with the following required scopes: https://www.googleapis.com/auth/userinfo.email. https://www.googleapis.com/auth/firebase.database. Using the Google API Client Library for Node.
As a resume (to me and maybe others) from @James-Poag answer, use:
curl 'https://www.googleapis.com/identitytoolkit/v3/relyingparty/verifyPassword?key=[API_KEY]' \
-H 'Content-Type: application/json' \
--data-binary '{"email":"[[email protected]]","password":"[PASSWORD]","returnSecureToken":true}'
Where:
password(string): The password for the account.
returnSecureToken(boolean): Whether or not to return an ID and refresh token. Should always be true.
The property idToken from response payload is the parameter you're looking for.
