Plugins

DeepSeek Harness plugin: give your agent a browser with a persistent identity - engine-level fingerprint spoofing, unlimited free local profiles, Android device emulation, passkeys that survive, and residential proxy egress.

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.

The plugin half of the DSH Harmony native HarmonyOS client: native login through the host token exchange (optional Pocket ID passkey), session list and live updates, task overview, per-device notification levels and web session handoff. Published as a prebuilt tarball; no separate relay or gateway daemon is required.

WEB ONLY: designed specifically for the Web profile, NOT Electron Desktop. Windows support means Web on Windows, not the Desktop application; installing into Desktop can break startup or restart. Refresh immediately after installation or open /login; HTTP 401 on an old page means sign-in is required, not installation failure. Only an uninitialized data directory displays the temporary password; existing passwords survive reinstalling. Initialize in a trusted network and change the publicly displayed initial password immediately; passwords are never printed in terminal logs. Web lock screen, password/OTP/Passkey, persistent sessions and wallpapers; Windows Web power services can be enabled from the page. Linux/macOS need the bundled controller; npm updates require a dedicated managed install. Stopping interrupts active tasks. Auth kernel adapted from xbzbing/dsh-auth-gateway (MIT); do not co-install.
