Firebase 禁止谷歌身份验证（权限被拒绝）

Question

i am currently using firebase to trying authenticate users with google. I set up an angular project with my project1. While signing in anonymously into firebase, everything works as expected, if i change to signing in with google using the popup, it just breaks with the following error:

{
  "error": {
    "code": 403,
    "message": "Requests from referer https://project1.firebaseapp.com/__/auth/iframe?apiKey=SECRET&appName=%5BDEFAULT%5D&v=7.13.2&usegapi=1&jsh=m%3B%2F_%2Fscs%2Fapps-static%2F_%2Fjs%2Fk%3Doz.gapi.en_GB.TVMmU0ureXg.O%2Fam%3DwQE%2Fd%3D1%2Fct%3Dzgms%2Frs%3DAGLTcCNEZ47O4XPxvOHlE2OsKBWeCQxiEw%2Fm%3D__features__ are blocked.",
    "errors": [
      {
        "message": "Requests from referer https://project1.firebaseapp.com/__/auth/iframe?apiKey=SECRET&appName=%5BDEFAULT%5D&v=7.13.2&usegapi=1&jsh=m%3B%2F_%2Fscs%2Fapps-static%2F_%2Fjs%2Fk%3Doz.gapi.en_GB.TVMmU0ureXg.O%2Fam%3DwQE%2Fd%3D1%2Fct%3Dzgms%2Frs%3DAGLTcCNEZ47O4XPxvOHlE2OsKBWeCQxiEw%2Fm%3D__features__ are blocked.",
        "domain": "global",
        "reason": "forbidden"
      }
    ],
    "status": "PERMISSION_DENIED"
  }
}

If i change my firebaseConfig from project1 to project2 (options like Google auth enabled, etc. are the same) it works properly. Hence it can't be a client-issue. Same error occurs by running locally and hosting by firebase.

I have absolutely no clue why is that, i am sure there has to be something obvious in the firebase settings which i just can't figure out yet. As far as i can tell, i changed all kinds of options on the firebase-platform itself.

To answer my own question: Go to google cloud console -> Credentials -> OAuth 2.0 Client IDs -> Select your project and add a 'Authorised redirect URI':

' https://myproject.web.app/ /auth/handler ' or ' https://myproject.firebaseapp.com/ /auth/handler '
