How to change Firebase user login identity from command line (CLI)?

I'm trying to login to Firebase using login credentials of, let's say, User-Alice.

But when I go through the authorization procedure I get a message saying I'm logged in as User-Bob. This is not mentioned anywhere in the documentation nor does it explain how to change the user I'm logged in as.

How can I change the Firebase logged in user from User-Bob to User-Alice?

Thank you.

Manage multiple users via the CLI

You can manage multiple users without re-authenticating, as of version 9.9.0 of the Firebase CLI.

firebase login:add
firebase login:list
firebase login:use

Example:

firebase login:add david@example.com
firebase login:add alice@example.com
firebase login:add bob@example.com
firebase login:use alice@example.com
firebase login:list
firebase deploy --only hosting # deploy as [email protected]

Get a URL printed to the terminal.

firebase login --reauth

Use that link in the browser with the needed profile.

Still working, less convenient older answer

The easiest way to handle this is to logout User-Alice and the login User-Bob.

firebase logout
firebase login

But, if you're logged as User-Alice with a Google account in the browser you'll need to sign out there first.

use this

firebase login --reauth

then you can change account

In the recent release of Firebase CLI (9.9.0) there was support for multiple accounts via new commands:

• login:use
• login:add
• login:list

Reference: https://github.com/firebase/firebase-tools/tree/v9.9.0

So I used firebase login:add to add a new account and then switched to newly added account use firebase login:use

Command for logout and login

firebase logout
firebase login

You can get token string by this command.

firebase login:ci

Then set it to FIREBASE_TOKEN env.

You can keep any number of tokens and set it automatically by some utils like dotenv.

Here are a few solutions:

firebase logout
firebase login

Or,

firebase login --reauth

First, your currently log in Google account must include 'User Alice'([email protected]) in your default browser. When you firebase logout and then Firebase will say

$ firebase logout
Logged out form '[email protected]'

firebase login, Firebase will open a browser and get the comfirmation (allow or deny). When you accept/allow, you can see the following in your terminal.

$ firebase login
Allow Firebase to collect anonymous CLI usage information? Yes

Visit this URL on any device to log in:
https://accounts.google.com/o/oauth2/auth?client_id=....

Waiting for authentication...

Success! Logged in as '[email protected]'

You have to log out of Google Accounts in (using) your primary browser (say, Safari). And log in to that same browser as the correct user. Trying to login to secondary browsers (say, Opera or Chrome) won't work. It needs to be the same browser that Firebase CLI opens automatically after hitting firebase login. Secondary browsers will be ignored.

If you have different google accounts - I recommend you have different browser user profiles for it in Google Chrome.

Before you enter firebase login, make sure you activate the respective browser window with the desired user profile.

This way you will not have to enter passwords again when switching accounts.

In 2021, Try (In Windows Powershell):

firebase login:ci --interactive

It will generate a token that you will set in your subsequent instructions. i.e. To init,

firebase init --token "secret-token"
