01 / 11What it does

Your PCs at hand. Wherever you are.

The account is optional and free. MoLock fully protects your PC without it — the account brings your PCs together and puts them in reach from anywhere.

  • All your PCs

    Status, lock state, battery, health and last seen — for every linked PC.

  • Instant actions

    Lock, photo, screenshot, siren, message, restart or shut down — delivered in moments.

  • Lost mode

    A contact message on the lock screen, regular photos and the approximate location.

  • Approve from your phone

    Someone at your PC asks to unlock; you allow once or deny.

  • Notes & clipboard

    Notes, to-dos, reminders, sticky notes and clipboard — encrypted.

  • Files & links

    Move files between phone and PC, and share them with encrypted, expiring links.

02 / 11Signing in

Your password, then a code on Telegram.

No text messages, no extra apps: the second step arrives from the official bot in the Telegram you already use.

  • Your Telegram usernameYour account is tied to your Telegram account itself — no phone number, no email.
  • Your account passwordBy default it is your PC's lock password, and you can change it any time. The password itself is never sent to the service.
  • A 6-digit codeSent by @MoLockOfficialBot, valid for 5 minutes — or use the Log in with Telegram button.
  • "Trust this browser"Keeps you signed in for 30 days on your own device; otherwise the session ends after 12 hours.

04 / 11Two bots, two jobs

The official bot and your own bot.

The personal bot you created at setup stays exactly as it is, with every command. The official bot @MoLockOfficialBot adds what a bot running on your PC cannot: it answers while the PC is off, brings your PCs together and sends sign-in codes.

Official bot commands

05 / 11Remote control

    If you left the MoLock Vault open.

06 / 11Lost mode

  1. T+0:00On

    You switch on Lost mode

    From your account, with a contact message and the photo interval you want.

  2. T+0:01Lock

  5. T+…Back

    You get it back

08 / 11Files & links

Share a file. Keep the key.

The file is encrypted on your PC or in your browser with a random key, and the key lives only in the link — in the part no browser ever sends to a server.

  • An expiryFrom 1 hour to 30 days, or delete after the first download.
  • An optional passwordA second layer, in case the link reaches the wrong person.
  • A download limitAfter that, the link stops working.
  • Between your phone and PCPrivate, end-to-end encrypted transfers that land in a MoLock folder inside Downloads.
  • Through the official botSend a file up to 20 MB and it is saved in your files with a share link. These are stored encrypted by the service but not end-to-end — they already passed through Telegram — and they are clearly labelled.

09 / 11Security, plainly

What is encrypted, and what is seen.

Your privacy does not rest on a promise: your content is encrypted before it leaves your PC, and its keys never reach the service.

End-to-end encrypted

Readable only by you

  • Notes, to-dos and reminders
  • Sticky notes and clipboard items
  • Attempt photos, and photos/screenshots taken remotely
  • Vault keys
  • Share-link files and private transfers
Never seen by the service

Never leaves your PC or browser

  • Your account and lock passwords
  • Encryption keys in usable form
  • The key of any share link
  • Your files and what you type on your PC
What the service does see

The little it needs to work

  • Your Telegram username and user ID
  • Your PC names, status and last seen
  • That an item exists, its type, time and size
  • For each sign-in: time, result, approximate city, browser type
  • The log of remote actions on your account

End-to-end encryption in plain wordsPrivacy policy

10 / 11Limits & guarantees

Plain numbers. Honest promises.

  • 5mina sign-in code stays valid
  • 30dayslongest session in a trusted browser
  • 2GBfile storage per account · files up to 100 MB
  • 24ha synced clipboard item lives by default (pinned: 30 days)
  • Nothing in the account can lock you out

    The account never changes your lock password or keeps you out of your PC. Any unlock from the account needs your signed-in session and is always reported to you.

  • Every PC has its own secret key

    Your PC signs every request with a key that never leaves it (kept in its security chip when there is one), so a stolen token alone cannot impersonate your PC.

  • Every change is announced

    A new account password, a newly linked PC or a sign-in from a browser — you hear about it.

  • Unlinking is instant

    From the account, the bot or the PC: commands to that PC stop at once.

  • If you forget the account password

    Nobody can recover it — not even the developer. Your data on your PC is not lost, and you can set a new password from MoLock on your PC.

11 / 11Questions

About the account

All questions

What is MoLock Account?

One account for every PC that runs MoLock. Open it from any browser to see each PC's status (locked or unlocked, online or offline) and control it remotely: lock, camera photo, screenshot, siren, an on-screen message, restart or shut down, locate and Lost mode. It also holds your notes, to-dos, reminders, sticky notes, the unlock history with photos, your files and share links. The account is tied to your Telegram account and guarded by the official bot, @MoLockOfficialBot, which sends your sign-in codes and reports every sign-in and every action. Take the tour.

Do I need an account, and is it free?

The account is free and entirely optional. MoLock works fully without it: locking, intruder photos, alerts, your personal Telegram bot and the tools. The account adds what a single PC can't do on its own: controlling several PCs from one place, reaching your data even while the PC is off, Lost mode, approving an unlock from your phone and share links. No email address is needed — your Telegram account is enough.

How do I sign in to my account?

Enter your Telegram username and your account password, and the official bot, @MoLockOfficialBot, sends you a 6-digit code that is valid for 5 minutes. Type it in and you're in. Instead of the code you can also use the Telegram login button. Tick "Trust this browser" to stay signed in for 30 days; otherwise the session ends after 12 hours. The bot reports every sign-in, successful or failed, and the sessions list lets you end any session or sign out everywhere.

What's the difference between the official bot and my personal bot?

The official bot, @MoLockOfficialBot, is run by MoLock — one bot for everyone that recognises you by your Telegram account. It works even when your PC is off, sends your account sign-in codes, lists your PCs with quick-action buttons, receives files and reports every sign-in and action. Your personal bot is the one you created yourself; it runs through MoLock on your PC with the full command set (camera, screen, files, power and more) and answers whenever your PC is on. Both keep working side by side; neither replaces the other. Official bot commands.

How do I link a PC to my account?

Open MoLock Settings → Account to see a link code such as ABCD-EFGH. It is valid for 10 minutes and can be used once. Send /link ABCD-EFGH to the official bot, or type the code on the account page while signed in. Within seconds the bot confirms that the PC is now linked to your account. If you don't have an account yet, it is created when you link your first PC. Step-by-step guide.

What is my account password?

By default it is the same as your PC's lock password, so there's nothing new to remember. If your lock password is shorter than 8 characters, MoLock asks once for a stronger account password. You can change it at any time on the account page or in the app, and the official bot reports every password change and every PC linked to your account. The password itself is never sent to the service.

Can the account unlock my PC, or lock me out of it?

Nothing in the account can lock you out: your lock password and recovery code always work as before. An unlock from the account requires your signed-in session (password plus bot code) and is always reported to Telegram. "Approve unlock" requests sent from the lock screen expire after 2 minutes, with at most 3 requests per 10 minutes per PC, and each approval unlocks the PC once and is logged.

What is Lost mode?

If your PC is lost or stolen, turn on Lost mode from your account or the official bot. The PC locks at once, the lock screen shows a message with how to reach you for whoever finds it, a camera photo is taken at the interval you choose, and the approximate location is sent whenever the PC is online. If the PC is off or offline, the command runs as soon as it connects. Switch it off with one tap once you have it back. Lost mode, minute by minute.

How private are share links?

The file is encrypted on your PC or in your browser before upload, with a random key that lives only inside the link (the part after the # sign). That part never reaches the service, so nobody without the link can open the file. You choose how long it lasts (1 hour to 30 days) and can add a password, limit the number of downloads or delete the file after the first download. Files you send to the official bot are stored encrypted by the service but not end-to-end, because Telegram already had them — and they are clearly labelled that way.

How much storage do I get for files?

Each account has 2 GB. A single file can be up to 100 MB when uploaded from the account page or the app, and up to 20 MB when sent to the official bot. Files stay until you delete them, and share links disappear on their own when they expire.

Can I control my full desktop from the browser?

Not yet. In 2.7 the account offers quick actions (lock, photo, screenshot, siren, message, restart or shut down, locate and Lost mode). Full remote desktop in the browser is coming in 2.8. Until then, /remote in your personal bot is still available for live control.
