This is real, server-verified authentication. Your password is checked against a
hash stored in the server's database (PBKDF2, never plaintext) — the browser never holds a
password, a key, or anything that decrypts data on its own. A secure session cookie (set by
the server, unreadable by this page's JavaScript) is what keeps you signed in. Your
templates and interviews are private to your account; the server also holds the Anthropic
and Groq API keys, so you never need your own.
