Fix: Cannot Sign In to Claude with Google Account

Why Google Login Fails on Claude

Using "Continue with Google" relies on a secure handshake between Google's identity servers and Anthropic's platform. When this fails, you may see a spinning loading wheel, an "Error logging in" message, or a blank page. The most common causes are blocked third-party cookies, aggressive privacy extensions, or an email mismatch between different authentication methods.

How to Resolve Google Sign-In Failures

1. Enable Third-Party Cookies and Cross-Site Tracking Google OAuth authentication requires your browser to temporarily store cookies across both the Google and Claude domains. * **On Chrome:** Go to `Settings` > `Privacy and security` > `Third-party cookies` and ensure they are not blocked. * **On Safari:** Go to `Settings` > `Safari` > `Privacy` and toggle off **Prevent Cross-Site Tracking** temporarily during login. * Try logging in again after updating these settings.

2. Disable Privacy Extensions and Ad Blockers Privacy-focused browser extensions (such as uBlock Origin, Privacy Badger, or Brave Shields) often block the scripts required for Google OAuth to run safely. * **What to do:** Turn off your ad-blocker or tracking shield for `claude.ai`. * Refresh the page and try clicking "Continue with Google" again.

3. Clear Google Session and Browser Cache Stale session data on either Google's or Claude's side can disrupt the handshake process. * **What to do:** Open a new tab and sign out of your Google account entirely. * Clear your browser's cache and cookies for the past 24 hours. * Navigate back to `claude.ai`, click "Continue with Google," and enter your credentials fresh.

4. Switch to Email Sign-In (Passwordless Link) If the OAuth pathway is completely blocked by your network or browser security configurations, you can access the same account using the passwordless email link option. * **What to do:** Instead of clicking the Google button, type the exact Gmail address associated with your Google account into the standard email field on the Claude login page. * Click **Continue with email**. * Open your Gmail inbox, locate the login link sent by Anthropic, and click it to log directly into your existing profile.

5. Disable VPNs or Secure DNS Some Virtual Private Networks (VPNs) and secure DNS configurations block port 443 redirections or flag Google’s identity APIs as trackers. * **What to do:** Temporarily disconnect your VPN or switch to your network's default DNS server. * Complete the login sequence, then re-enable your secure connection.

When to Escalate

If you receive a specific error stating your account is disabled or suspended during the login attempt, this indicates an account-level restriction rather than a browser bug.

For persistent technical sign-in loops, contact Anthropic Support via the Help button on the support site. Let them know whether you are using a workspace/workspace-managed Google account, as administrator settings on your company's Google Workspace can sometimes block third-party integrations like Claude.
