Troubleshooting login

Resolve common login and SSO issues for Warp Enterprise users and IT admins. For SSO setup and configuration, see Single Sign-On (SSO).

SSO login issues

Can’t open Warp from your SSO provider

When launching Warp directly from Okta or another SSO provider’s app dashboard, you may see an error like “Unable to process request due to missing initial state.” This is a known limitation with the authentication flow.

To fix it:

1. Go to the Warp login page.
2. Choose Continue with SSO.
3. Log in with your normal SSO credentials.

Previously logged in with another method

If you originally created your Warp account with email, Google, or GitHub and now need to use SSO:

1. Go to the Warp login page.
2. Log in with your original method (email, Google, or GitHub).
3. Once logged in, visit the SSO linking page.
4. Click Link SSO to connect your existing account. You can now use Continue with SSO going forward.

Note

IT admins: if multiple team members need to link their accounts to SSO, share these steps during your SSO rollout.

Common login issues

Can’t sign up or log in

If clicking the sign-up or login button opens a blank popup or nothing happens:

• Your ISP or firewall may be blocking calls to *.googleapis.com. Try using a proxy or allowlisting this domain.
• In some older Ruby development environments, .dev domains don’t resolve properly. If applicable, delete /etc/resolver/dev (see fixing .dev domain resolution).

Browser-specific issues

If you see authentication errors or blank popups across browsers:

1. Disable ad blockers for app.warp.dev.
2. Clear cookies and cache, or try an incognito / private browser window.
3. Try the Warp login page again.

Safari-specific: If you see “Unable to access localStorage” errors, go to Safari Preferences > Privacy and uncheck Block all cookies. Firebase Auth requires cookies to track login state.

Proxy issues

If you’re behind a proxy, QUIC traffic may not pass through correctly. Disabling QUIC in your browser forces a fallback to TCP, which typically resolves the issue:

Chrome / Chromium-based browsers (Edge, Opera, Arc):

1. Navigate to chrome://flags.
2. Search for Experimental QUIC protocol.
3. Set it to Disabled.
4. Relaunch the browser.

Firefox:

1. Navigate to about:config.
2. Accept the risk warning.
3. Search for network.http.http3.enable.
4. Double-click to set it to false.
5. Restart Firefox.

Safari: There is no built-in option to disable QUIC in Safari.

Flagged as fraudulent

If you see “This account has been flagged as fraudulent,” your account has triggered Warp’s fraud detection system. This can happen due to multiple account creation or use of throwaway emails (both against Warp’s Terms of Service).

False positives

Ad blockers or systems like Pi-hole can sometimes trigger false positives. Try temporarily disabling them and attempting login again.

Requesting an appeal

If you’re still unable to authenticate, email appeals@warp.dev with the email address of the affected account. Appeals may take 5–10 days.

Enterprise customers can also contact their account manager or dedicated Slack/Teams channel for faster resolution.

Browser doesn’t open when signing in

If the browser doesn’t open automatically from Warp when you click “Sign up” or “Sign in”:

1. Go to the Signup or Login page in your browser.
2. Complete authentication in the browser.
3. On the logged-in page, if Take me to Warp doesn’t work, click the token-copy link to copy the authentication token.
4. Paste the token into Warp.

Note

On Linux and Windows, the default paste shortcut is Ctrl+Shift+V.
