Gemini Sign In Loop: How to Fix Redirect Errors

Getting stuck in a continuous redirect loop when trying to sign in to Google Gemini (gemini.google.com) is a frustrating but common issue. You enter your credentials, the page redirects, and instead of loading the chat interface, you are kicked back to the login page or stuck on a pulsing loading logo.

This guide provides concrete, sequential troubleshooting steps to resolve the Gemini sign-in loop and regain access to your account.

1. Verify Your Google Account Type

Gemini has strict access rules depending on whether you are using a personal Gmail account or an enterprise/educational Google Workspace account.

1. Check for Workspace restrictions: If your email ends in a custom domain (not @gmail.com), your organization's IT administrator must explicitly enable Gemini access in the Google Admin console. If disabled, the sign-in process will fail silently or loop.
2. Verify age requirements: Google accounts managed via Family Link or those under the age of 18 (or the applicable age in your country) cannot access Gemini Advanced, and may face login loops on standard Gemini if parental permissions are not configured correctly.
3. Switch to a personal account: Try signing out of all Google accounts in your browser, then log in using a standard, personal @gmail.com address to see if the loop resolves.

2. Clear Google-Specific Cookies and Site Data

Corrupted session tokens and expired cookies frequently trigger authentication loops. Instead of clearing your entire browser history, you can clear data specifically for Google and Gemini.

1. On Google Chrome: Open gemini.google.com. Click the site settings icon (the sliders or padlock icon) to the left of the URL in the address bar.
2. Select Site settings or Cookies and site data, then click Manage on-device site data.
3. Click the trash can icon next to all listed domains (such as google.com and gemini.google.com) to delete them.
4. Alternatively, open Chrome Settings (chrome://settings/siteData), search for "google", and delete the stored cache and cookies.
5. Restart your browser and attempt to sign in again.

3. Resolve Multi-Account Login Conflicts

Logging into multiple Google Accounts simultaneously in the same browser session often confuses Google's authentication handler, resulting in a redirect loop.

1. Go to [myaccount.google.com](https://myaccount.google.com).
2. Click your profile picture in the top-right corner of the page.
3. Click Sign out of all accounts.
4. Close all open browser tabs and windows.
5. Open a new browser tab, navigate directly to gemini.google.com, and log in with *only* the single account you wish to use with Gemini.

4. Enable Third-Party Cookies and Cross-Site Tracking

Gemini relies on cross-domain authentication to verify your Google identity. If your browser blocks third-party cookies or prevents cross-site tracking, the login process will fail to pass your credentials to the Gemini interface.

1. In Google Chrome: Go to Settings -> Privacy and security -> Third-party cookies. Ensure "Block third-party cookies" is not selected, or add [*.]google.com and [*.]gemini.google.com to your "Allowed to use third-party cookies" exceptions list.
2. In Apple Safari: Go to Settings/Preferences -> Privacy. Uncheck the option for Prevent cross-site tracking.
3. In Brave: Click the Brave Shield icon in the address bar while on the Gemini page and toggle it off to test if Brave's aggressive tracker blocking is stopping the authentication scripts.

5. Disable Browser Extensions and Ad Blockers

Privacy extensions, script blockers (such as NoScript), and aggressive ad blockers can block Google's security check scripts, causing the authentication flow to fail mid-way.

1. Open a private browsing session (Incognito mode in Chrome, Private Window in Firefox or Safari). This disables most extensions by default.
2. Go to gemini.google.com and log in within the private window.
3. If the login succeeds, the issue is caused by an extension in your main browser profile.
4. Return to your normal browser window, open your Extensions page, and disable your ad blocker or privacy extensions one by one to isolate the culprit.

When to escalate

If you have cleared your cache, disabled extensions, verified your account type, and still experience the sign-in loop, the issue may be account-level suspension or a Google-side authentication outage.

• Workspace Users: Contact your organization's domain administrator. They must navigate to the Google Admin Console -> Apps -> Additional Google Services and verify that Gemini is set to "ON for everyone".
• Gemini Advanced Subscribers: If you pay for Google One AI Premium, access the [Google One Help Center](https://support.google.com/googleone) while logged into your active account to request direct, priority chat or email support from a Google specialist.
