Cursor errors / Auth
Authentication blocked, please contact your admin
Cause
The Auth0 sign-in flow detects a policy restriction - an org SSO/email-domain block, a school/work network firewall, or a flagged account - and rejects the attempt.
Fix
Try signing in with a personal email (Gmail/GitHub) not subject to the blocked domain. Allowlist cursor.com / auth.cursor.sh in corporate SSO or firewall settings. If a school/work email, ask IT to whitelist auth.cursor.sh. If the account is flagged, email hi@cursor.sh with the details.
