The bot tells you it's time
"A maintenance update is available. Would you like me to open the window?" — the bot asks you, on the same Telegram channel you already use. It does not let anyone in until you say so.
You generate a one-time code
You reply yes, 30 minutes. The device generates a one-time code and shows it to you in your bot chat. The code is only valid for the duration you set.
The maintenance door unlocks
The device opens its maintenance channel, restricted to keys held by our on-call team, and requires the one-time code as a second factor. The on-call engineer is automatically paged with the time-bounded window.
We do the work, on camera
The engineer connects, performs the task, and disconnects. Their entire session — every keystroke, every file touched — is recorded to a file on your device, encrypted with your key. We don't keep a copy.
The door auto-closes
At the window's end, the maintenance channel locks. Even with a valid key, our engineers cannot reconnect until you open the next window.
You review, anytime
Whenever you want — that day, a year later — you can replay the session recording, verify the audit-chain hashes, and see exactly what we did. If anything was edited after the fact, the chain breaks and the device tells you.
