How to get authorisation code during angularfire installation?

Issue

During installation AngularFire by ng add @angular/fire I get following error

? Paste authorization code here: 1//0cpKD...
Authentication Error: Your credentials are no longer valid. Please run firebase login --reauth

For CI servers and headless environments, generate a new token with firebase login:ci

I try do put different code-like string from firebase site but no luck. I also try to run firebase login:ci, this generate long url, I copy it to browser and login to my google account, accept, and copy quite long token - but still no luck - it is wrong. How to get right authorization code?

Solution

I found following solution:

1. Run firebase login:ci --no-localhost
2. and open in browser generated link, login to your google account and accept
3. copy code (which is few times shorter than token (~62 chars)
4. TRICK: do NOT PASTE that code to console - but open new separate console
5. In new console run ng add @angular/fire
6. and paste that code during installation - now error not appear
