Claude Login Link Not Working? Fix Magic Link Issues

Accessing Claude.ai relies on a "magic link" passwordless login system. When you enter your email address, Claude sends a one-time login link to your inbox. If clicking this link does not log you in, or if the email never arrives, it is typically caused by session mismatches, strict browser security settings, or email server delays.

Follow these troubleshooting steps to resolve the issue and access your account.

1. Keep the original tab open The magic link system requires the session to remain continuous. When you request a login link, Claude places a session cookie on your browser. If you close the tab where you requested the login link, the security token changes. - Go back to Claude.ai and request a new login link. - Keep that exact browser tab open. - Open your email in a separate window or tab, find the email, and click the link. It should redirect back to the open session.

2. Copy and paste the link directly Email clients—especially Outlook (with Safe Links enabled), ProtonMail, or Gmail on mobile devices—sometimes rewrite URLs for security analysis. This rewriting breaks the authentication parameters in the login token. - Open the magic link email. - Right-click the "Sign in to Claude" button (or long-press on mobile) and select **Copy Link Address**. - Return to the browser tab where you initiated the login request. - Paste the copied link directly into the address bar and press Enter.

3. Clear cache and cookies for Anthropic domains Corrupted authentication state cookies can cause Claude to get stuck in a login loop, showing errors like "Invalid token" or taking you back to the login page repeatedly. - In your browser settings, navigate to **Privacy and Security**. - Select **Cookies and other site data**. - Search for `claude.ai` and `anthropic.com`. - Click **Clear data** or the trash icon next to these domains. - Restart your browser and try to log in again.

4. Disable aggressive tracking protection Strict ad-blockers, tracking blockers, and built-in browser security settings (such as Brave Shields or Firefox Strict Mode) can block the third-party redirects required to authenticate your login link. - Disable extensions like uBlock Origin, Privacy Badger, or Ghostery on the login page. - If using Brave, toggle down the Shields icon in the address bar. - If using Firefox, click the shield icon to the left of the URL and disable **Enhanced Tracking Protection** for Claude.ai.

5. Use Google or Apple sign-in bypass If you originally registered your account using a Google or Apple account, requesting an email magic link will often fail to authenticate correctly. - Return to the main login screen. - Click **Continue with Google** or **Continue with Apple**. - Authenticate through that provider. If you have multiple Google accounts, ensure you choose the specific email associated with your Claude profile.

When to escalate If you have completed these steps and still do not receive the email, or if every link says "Expired link," your email domain might be blocked or rate-limited by Anthropic's mail delivery system. Contact Anthropic Support via their help center. Provide your registered email, browser version, and specify that you have already attempted direct link copying and cookie clearing.
