Authentication gateway for the DeepSeek Harness Web UI: the login gate covers pages, /api, /plugins and WebSocket upgrades; PBKDF2 password hashing with per-user salts, HttpOnly SameSite session cookies named per DSH_HOME and IP-based login lockout; invite-code registration; two-factor login with TOTP or passkeys (WebAuthn: several keys per account, phone enrolment by QR, username-less sign-in, and a step-up before any login factor is added or removed); a user-management settings panel (users edit their own profile and manage their own TOTP and passkeys, admins add or remove users, reset passwords, manage invites and clear the passkeys of a lost device); per-user model and API-key configuration whose private entries are encrypted with a key derived from the login password and stay unreadable by any admin, with admin sharing to selected users (usable, balance visible, key never shown, revocation immediate) and unconfigured users blocked rather than falling back to the deployment configuration; per-user isolation on the REST and list APIs and per-frame ownership filtering on the WebSocket mux; session persistence across restarts; a JSONL audit log; and a fail-closed gateway. Requires the DSH 0.2.0 line (the 0.1.1-rc.2 transport line was removed in 0.7.0); passkey login needs a localhost or HTTPS origin because browsers require a secure context.
