Laravel Gmail package failing with multi-user authentication setup

I’m working with the Laravel Gmail package and having issues when trying to handle multiple user accounts. The package works perfectly when I use it with just one set of credentials, but as soon as I try to implement multiple user authentication, the login process breaks down.

I’ve configured everything according to the documentation - set up all the environment variables and updated the config file properly. The strange thing is that the credentials are being saved to the correct folder path, but the actual login functionality isn’t working.

Here’s what I’m trying to do:

public function handleCallback()
{
    $userIdentifier = 'account_' . mt_rand(1, 50);
    LaravelGmail::setUserId($userIdentifier)->generateToken();
    return redirect()->route('dashboard');
}

Has anyone successfully implemented this package with multiple user credentials? I’m open to alternative solutions or workarounds if this approach isn’t viable.

Hit the same issue 6 months back with multi-tenant Gmail integration. This isn’t usually an auth problem - it’s token storage conflicts. The Laravel Gmail package stores tokens in a way that creates race conditions when multiple users authenticate at once. Here’s what fixed it for me: ditch the default file-based storage and create a database table for OAuth tokens with proper user association. You’ll need to extend the package’s token handler and override the storage methods to use your DB instead of the filesystem. Also double-check your callback route handles Google’s state parameter correctly - that’s key for matching auth requests to the right user session. Without proper state validation, the package tries to associate tokens with the wrong user.

Check your callback URL setup for multi-user scenarios. I had the same headaches - turned out to be session conflicts between different auth flows. Store the userIdentifier in session before redirecting to Google auth, then grab it in the callback instead of generating random ones. Also, call logout() on the Gmail instance before switching users or tokens get mixed up.

Hit this exact problem building a multi-tenant email dashboard last year. The package screws up session state when different users authenticate. Your random identifier approach is probably the culprit - the package wants consistent user mapping through the entire auth flow. I fixed it by using actual user IDs from my app instead of random strings. Also clear the token cache before starting new auth flows. The package caches previous auth attempts in memory and they mess with each other. If you’ve got multiple users authenticating at once, set up a queue for token generation. Fixes the timing conflicts that break auth.
