Firebase - how to set custom claim from the console [duplicate]

Question

In my application I use firebase authentication and Google account as credentials provider. I would like to assign roles to users. In order to do it I would like to add custom claims to the authentication token a user gets during login. And here is my problem because I don't know how to add claims to existing user from the firebase console.

Answer 1

There is currently no way to set custom claims for a user in the Firebase console. If you think this would be a useful addition, file a feature request for it.

In the meantime the easiest way to add a custom claim is to do so from the a terminal window/command prompt using a small Node.js script like this:

admin.auth().setCustomUserClaims(uid, {admin: true})
