Firebase Authentication で このアプリは確認されていません とエラーが出た時 Firebase UI

こんな感じのエラーが出た時

これを

ui.start('#firebaseui-auth-container', {
  signInOptions: [
    {
      provider: firebase.auth.GoogleAuthProvider.PROVIDER_ID,
      scopes: [
        'https://www.googleapis.com/auth/contacts.readonly'
      ],
      customParameters: {
        // Forces account selection even when one account
        // is available.
        prompt: 'select_account'
      }
    },
    {
      provider: firebase.auth.FacebookAuthProvider.PROVIDER_ID,
      scopes: [
        'public_profile',
        'email',
        'user_likes',
        'user_friends'
      ],
      customParameters: {
        // Forces password re-entry.
        auth_type: 'reauthenticate'
      }
    },
    firebase.auth.TwitterAuthProvider.PROVIDER_ID, // Twitter does not support scopes.
    firebase.auth.EmailAuthProvider.PROVIDER_ID // Other providers don't need to be given as object.
  ]
});

こうする

ui.start('#firebaseui-auth-container', {
  signInOptions: [
    {
      provider: firebase.auth.GoogleAuthProvider.PROVIDER_ID,
      scopes: [
        'email'//ここを変える
      ],
      customParameters: {
        // Forces account selection even when one account
        // is available.
        prompt: 'select_account'
      }
    },
    {
      provider: firebase.auth.FacebookAuthProvider.PROVIDER_ID,
      scopes: [
        'public_profile',
        'email',
        'user_likes',
        'user_friends'
      ],
      customParameters: {
        // Forces password re-entry.
        auth_type: 'reauthenticate'
      }
    },
    firebase.auth.TwitterAuthProvider.PROVIDER_ID, // Twitter does not support scopes.
    firebase.auth.EmailAuthProvider.PROVIDER_ID // Other providers don't need to be given as object.
  ]
});

と出なくなるはず
