Login Issues

Having trouble logging into NorthSignal? Here are the most common causes and solutions.

1. Popup Blocker Is Active​

NorthSignal uses a Google OAuth popup for authentication. If your browser blocks popups, the login window will never appear.

The Fix:

  1. Check your browser's address bar for a "popup blocked" icon.
  2. Click it and select "Always allow popups from app.northsignal.cloud".
  3. Try the login again.

2. Ad Blocker / Privacy Extension Interference​

Some browser extensions (uBlock Origin, Privacy Badger, etc.) can interfere with OAuth redirects.

The Fix:

  1. Temporarily disable ad blockers or privacy extensions.
  2. Alternatively, add app.northsignal.cloud and accounts.google.com to your extension's allowlist.
  3. Retry the login.

3. Third-Party Cookies Disabled​

Google OAuth requires third-party cookies in some browsers. If they're completely blocked, authentication may fail silently.

The Fix:

  1. Go to your browser's Privacy/Cookie Settings.
  2. Ensure third-party cookies are not fully blocked (or add an exception for Google).
  3. Retry the login.

4. Test with Incognito / Private Mode​

If none of the above work, try logging in via an Incognito / Private Browsing window. This temporarily disables all extensions and uses default cookie settings, which helps isolate the issue.

  • Chrome: Ctrl+Shift+N
  • Firefox: Ctrl+Shift+P
  • Safari: Cmd+Shift+N

If login works in incognito, the issue is caused by an extension or cookie setting in your normal browser.
