🔐 Access Safety

Unattended Access Setup Set a Strong Password and Two Factor Authentication

Unattended access — reaching a PC when nobody is sitting at it — is the most useful and the most dangerous feature of every remote tool. Set up casually, it is a standing invitation into that computer. Set up properly, it is safe enough for your office. These are the settings that separate the two.

Every unattended setup, in AnyDesk, RustDesk or any other tool, stands on the same four legs: the program must run as an installed service (so it is alive at the login screen), it must ask for a real password (not a short PIN you reuse elsewhere), two-factor authentication should guard that password where the tool offers it, and the PC's power settings must not put it to sleep five minutes after you leave. This guide sets up all four, tool by tool where they differ.

Unattended access — safety checklist
☑ Program installed as a service (not just portable)
☑ Permanent password — long, unique, not reused
☑ Two-factor authentication enabled where offered
☑ PC sleep disabled or Wake-on-LAN configured
☑ Tested after a full reboot, at the login screen
☐ One-time codes shared with whoever asks  Never

👆 Five ticks make unattended access safe; the sixth box is how most remote-access fraud actually happens.

1

Install the Service — Portable Is Not Enough

A portable remote tool only exists while someone logged in keeps it open. For unattended access the program must run as a Windows service:

  1. In AnyDesk, use the installed version (the installer offers service installation); in RustDesk, click Install in the main window and approve the service prompt
  2. Confirm in services.msc that the tool's service exists and its startup type is Automatic
  3. Restart the PC and, without logging in, try connecting — reaching the Windows login screen remotely is the proof the service works

Set a Permanent Password Worth the Name

  1. AnyDesk: Settings → Security → unlock with administrator rights → enable Unattended Access and set the password
  2. RustDesk: Settings → Security → set a permanent password
  3. Use at least 12 characters, unique to this PC and this tool — a password manager generates and remembers a proper one
  4. Give each PC its own password. One shared password across the office means one leaked password opens every door

Treat this password like the office key, because functionally it is one: anyone holding it can walk in at 3 a.m. Change it when a staff member who knew it leaves, exactly as you would change a lock.

Add Two-Factor Authentication Where Offered

A password can be guessed, phished or reused by mistake; a second factor breaks all three. AnyDesk offers two-factor authentication for unattended access: in the same Security settings, enable Two-Factor Authentication and scan the code with an authenticator app — after the password, connections also need the current code from your phone. RustDesk deployments that use accounts (including the self-hosted Pro setup) likewise support two-factor sign-in.

Save the recovery codes the tool shows you, somewhere offline. The same factor that locks attackers out will lock you out after a lost phone if you skip this.

Power, Lock Screen and the Final Test

  1. Set the PC's sleep timer to Never while plugged in (Settings → System → Power), or configure Wake-on-LAN properly and test it — a sleeping PC is the number one "unattended access stopped working" cause
  2. Let the screen lock normally — locking is good; the service still accepts your connection and you unlock remotely
  3. Do the honest test: reboot, wait at the login screen, connect, log in, restart an app, disconnect
  4. Finally, review who else knows the password and the ID — and remove anyone who should no longer have them
🛑 The golden rule: unattended access is for machines YOU reach. The moment a stranger on a phone call asks you to install a remote tool, set a password, or read out a code, the setup stops being support and becomes a robbery in progress — see the scam-safety page in this series.

❓ Frequently Asked Questions

Is a permanent password alone safe enough for unattended access?

A long, unique permanent password on an installed, updated tool is a reasonable baseline for home use. For office machines, add two-factor authentication where the tool offers it, give every PC its own password, and review access when staff change. Short or reused passwords are the setup that actually gets people compromised.

Why can I not connect after the PC restarts?

Almost always one of two causes: the tool is running portably instead of as a service, so nothing is alive at the login screen; or the PC went to sleep. Install the service, set startup to Automatic, and adjust the sleep settings — then test with a real reboot.

Should I write the unattended password down?

Write it into a password manager — that is what they are for. A note stuck to the monitor defeats the entire setup, and a password you 'remember' by reusing your email password is worse than either.
