Security Check

Why this appears: Cloudflare Turnstile couldn't load on this device (no connection to Cloudflare, ad-blocker, or VPN).
How the offline check works: this server gives your browser a one-time challenge; your device finds a number (nonce) so that SHA-256(challenge:nonce) starts with enough zero bits — a small proof-of-work that takes a few seconds (watch the progress bar). The server re-checks it once, then burns it: each challenge works once and only for the username you typed.

We use essential cookies only

Login, security check, and device protection. No analytics or ads. These cannot be turned off without breaking sign-in.

sessionid — keeps you signed in (8h max).
csrftoken — protects forms from forgery.
caufa_device_id — remembers this browser for zero-trust checks.
caufa_device_proof — HttpOnly device secret, never readable by scripts.
