Zenta gives every computer a permanent ID and a password that rotates every 60 seconds — the connect flow you already know, built on open infrastructure you run yourself for free.
Built for the moment someone needs help on their computer right now, and for the machines you want to be able to reach again without anyone present.
A 9-digit ID stays the same forever. The one-time password refreshes automatically every 60 seconds, so a stale credential is never enough to get in.
Not a read-only screen share. The desktop app injects native OS input, so the person helping you can actually drive the machine — not just watch it.
Set a second, fixed password once and reconnect any time — nobody needs to be sitting at the keyboard to read out a fresh code.
Repeated wrong guesses lock the device out with escalating backoff. Every password is stored as a PBKDF2 hash, never in the clear.
One script stands up the full stack behind a Cloudflare Tunnel on Oracle Cloud's Always Free tier — no open ports, no certificate to manage, no bill.
Ad-hoc support needs nothing but an ID and a password. There's no license to buy and no seat count to manage.
Read out the 9-digit ID and the current password — or set a fixed one first for unattended access.
Your partner enters both on the connect screen. Viewing works from any modern browser — no install required to watch.
Once the desktop app is sharing, mouse and keyboard control arms itself the moment they connect. No extra prompts.
So it's treated like one.
Both the rotating and unattended passwords go through PBKDF2-HMAC-SHA256 with 200,000 iterations before they ever touch disk.
Passwords are drawn from a 32-symbol alphabet with no 0/O or 1/l/I confusion, so reading one aloud over a call never gets mistyped.
Five wrong guesses locks a device out for 30 seconds, then 2 minutes, then 10 — and rotating the password never resets an attacker’s lockout.
A device's permanent ID can only be reclaimed by whoever holds its private ownership secret — nobody can hijack an ID they don't already control.

“Typical hosted tool” describes the common shape of proprietary, cloud-hosted remote-support products in general — check any specific vendor's current plans before you decide.
Yes. There's no billing system in the product at all — you self-host it on a free-tier VPS (the docs walk through Oracle Cloud's Always Free ARM tier) and there's no per-seat or subscription cost.
Not for ad-hoc support. The ID + password flow works with no sign-up at all. A separate account system exists if you want saved contacts and share requests, but it’s optional.
Full control, not just viewing. Once the desktop app is sharing your screen, mouse and keyboard control is armed automatically the moment your partner connects.
It’s a second, fixed password you set once (separate from the one that rotates every 60 seconds) so you or a trusted partner can reconnect later without anyone at the keyboard to read out a fresh code. Turn it on from the connect screen.
No — you run it yourself. That’s the point: one script deploys the whole stack behind a Cloudflare Tunnel, so nothing is billed and nobody but you operates the server.
The computer being controlled needs the Windows desktop app for full input control. Whoever is helping can connect from any modern desktop browser — no install required to view.
Get your ID, share the current password, and you're connected.
