One click, and your progress follows you.

Sign in to keep your solves server-side, continue on any device, and have your certificates always available for verification. We use OAuth only — there are no passwords on this site, so nothing credential-shaped can leak from us.

Sign-in isn't configured on this deployment yet.
Operator: open /securemindaup and paste your GitHub client id + secret under “Sign-in providers”. See SECURITY.md.

Signing in stores: your provider id, a display name, a random public account id (for certificate verification), your solved labs, and issued certificates. Nothing else. You can play every lab without an account — progress then stays in this browser only.
