It locks when you leave. It knows when you're back.
Walk-away lock that doesn't guess. MoLock combines your phone, watch or earbuds over Bluetooth, your phone on the same Wi-Fi, your keyboard and mouse — and, only if you want, the camera — before it decides you have left. A short countdown, then the lock. When you come back, a calm welcome and, if you allow it, one key to get back in.

01 / 08How it works
Pair, walk, forget about it. That's the setup.
Presence works entirely on your PC. The dashboard and the bot add history, remote settings and alerts — never the decision itself.
- 01Step 1/3
Choose your signals
Pick a phone, watch, band or earbuds you already paired — or choose one from a scan. Add your phone on the home Wi-Fi and keyboard/mouse activity. The camera stays off unless you turn it on.
- 02Step 2/3
Do the one-minute walk test
Walk away from your desk and come back. MoLock learns where your desk ends and sets two thresholds — one for leaving, one for returning — so it never flickers at the edge.
- 03Step 3/3
Walk away
When the signals agree you have left, a short countdown appears with a Cancel button, then the screen locks. Come back and a welcome screen greets you, with quick unlock if you enabled it.
02 / 08What it does
Many signals. One calm decision.
A single Bluetooth signal is fragile: phones sleep, pockets and walls weaken the radio. MoLock weighs several signals together and only locks when it is confident.
Phone, watch, earbuds
Paired devices or one chosen from a scan, with smoothing so a single weak reading never locks you out.
Phone on the same Wi-Fi
A second, independent sign that you are nearby — useful when Bluetooth naps.
Activity
Typing or moving the mouse means someone is here — it keeps the PC awake and feeds the alerts.
Camera presence (opt-in)
Off by default. When on, frames are checked on the PC for a face and thrown away — never stored, never uploaded.
Grace countdown
A toast with Cancel before every automatic lock — you choose its length.
Welcome back
Optional quick unlock with one key or a PIN within the minutes you choose.
Strict quick-unlock rules
Never offered after wrong-password attempts or a remote lock — then the full password is required.
Someone typing while you're away
An alert on Telegram and in the dashboard, with a Lock now button.

03 / 08Your day, at a glance
A timeline of away and back. Not a surveillance log.
The dashboard shows when the PC locked because you left and when you came back — the signals behind each decision, and nothing about what you did on the PC.
- Present / away bandsEvery auto-lock, every return, and how long you were away — kept up to 400 days, end-to-end encrypted.
- The moments that matterTyping while your phone was away, a cancelled lock, a remote lock — marked clearly.
- Tune it from anywhereChange the countdown, the signals or quick unlock in the dashboard; the PC applies it when it is online.
04 / 08Privacy
Presence stays on your PC.
The decision to lock is made on the PC, offline. Only the timeline you can see in the dashboard leaves it — sealed with your account key.
Camera frames never leave
The optional camera signal looks for a face in memory and discards the frame at once. No photo is ever saved or sent.
End-to-end encrypted history
Away/back times are sealed on the PC; the server stores data it cannot read.
Your password still rules
Presence adds convenience on top of your password — it never replaces it.

The dashboard decides. The bot follows.

06 / 08Limits
Exactly what it does. And what it doesn't.
Bluetooth helps a lot
Without Bluetooth on the PC, presence relies on Wi-Fi, activity and the optional camera. Most laptops have it; many desktops need a small adapter.
Radio distance is approximate
Walls, pockets and bodies change the signal. That is why there is a walk test, two thresholds and a countdown.
Sleepy phones
Some phones quiet their Bluetooth to save battery. Combining several signals keeps that from causing false locks.
Not a replacement for a password
Quick unlock is a convenience with strict rules; your password remains the real key.

In-depth guides. In plain words.
Walk-away lock, done right
A lock that follows you sounds simple until it locks while you are reading, or stays open because your phone is still on the desk. Here is what goes wrong with single-signal proximity locks, and how MoLock decides that you have really left.
Approve unlock from your phone: the story behind it
Sooner or later someone needs your PC while you are somewhere else. Until now the only answer was to read your password over the phone. MoLock 2.7 gives you a better one: a request on the lock screen, a photo on your phone, and a single tap.
Privacy guard: cameras, microphones and shoulder surfers
The webcam light tells you that something is watching, not who. MoLock's privacy guard answers the real questions — which app, when, and was that supposed to happen — and adds a quiet defence against the person sitting next to you.
08 / 08Questions
Walk-away lock
Does walk-away lock need Bluetooth?
It works best with Bluetooth on the PC, so it can sense your phone, watch or earbuds. Without it, MoLock still uses your phone on the same Wi-Fi, keyboard and mouse activity and — if you turn it on — the camera.
Will it lock while I'm still at my desk?
It is built not to. Several signals must agree, a one-minute walk test sets separate "away" and "back" thresholds, and a countdown with a Cancel button appears before every automatic lock. Typing or moving the mouse always counts as being here.
How does quick unlock stay safe?
Quick unlock (one key or a short PIN) is optional and only available for the minutes you choose after your devices come back. It is never offered after wrong-password attempts or when the PC was locked remotely — then your full password is required.
Is the camera used to watch me?
No. Camera presence is off unless you turn it on. When it is on, each frame is checked on the PC for a face and discarded immediately — nothing is saved or uploaded.
