-# AnyDesk-Unattended-Setup
+# AnyDesk Unattended Access Installer for Linux Mint
 
+A Bash script that installs AnyDesk from the official repository on Linux Mint (and other Debian/Ubuntu-based systems) and sets a password for unattended access.
+
+## What it does
+
+1. Verifies it is running as root on an apt-based system.
+2. Gets the unattended access password (from an environment variable or an interactive prompt).
+3. Adds the official AnyDesk apt repository and GPG signing key.
+4. Installs AnyDesk and enables its systemd service.
+5. Sets the unattended access password via stdin, so it never appears in the process list.
+6. Prints the AnyDesk ID so you can connect right away.
+
+## Requirements
+
+- Linux Mint (tested target), or another Debian/Ubuntu-based distribution
+- Root access (`sudo`)
+- Internet access to `keys.anydesk.com` and `deb.anydesk.com`
+- An **X11** desktop session (the Linux Mint default). AnyDesk does not support Wayland.
+
+## Usage
+
+Make the script executable:
+
+```bash
+chmod +x install_anydesk_unattended.sh
+```
+
+### Interactive
+
+You will be prompted for the password twice (input is hidden):
+
+```bash
+sudo ./install_anydesk_unattended.sh
+```
+
+### Non-interactive
+
+Pass the password as an environment variable, useful for automation or deploying to multiple machines:
+
+```bash
+sudo ANYDESK_PASSWORD='your-long-password' ./install_anydesk_unattended.sh
+```
+
+Note that `sudo VAR=value` keeps the value out of the process arguments of the script, but it will still be stored in your shell history. Clear it afterwards, or read the value from a secrets manager or protected file instead:
+
+```bash
+sudo ANYDESK_PASSWORD="$(cat /root/anydesk_pw)" ./install_anydesk_unattended.sh
+```
+
+## Output
+
+On success the script prints something like:
+
+```
+AnyDesk installed and unattended access password set.
+AnyDesk ID: 123456789
+```
+
+Use that ID and the password you set to connect from another AnyDesk client.
+
+## Password requirements
+
+The script enforces a minimum of **10 characters**. Use a long, unique password.
+
+## Security recommendations
+
+- Use a strong, unique password. An exposed AnyDesk ID with a weak password is a common way machines are compromised.
+- If your AnyDesk plan supports it, enable two-factor authentication and an access control list (allowlist of permitted AnyDesk IDs) in AnyDesk's settings.
+- Avoid leaving the password in shell history, scripts under version control, or world-readable files.
+- Disable or uninstall AnyDesk on machines that no longer need remote access.
+
+## Limitations
+
+- The machine must be powered on and at the login screen or logged in. AnyDesk cannot wake a sleeping or powered-off machine (use Wake-on-LAN or similar for that).
+- Wayland sessions are not supported.
+- Re-running the script is safe: it reinstalls/updates the package, rewrites the repo entry, and resets the password.
+
+## Troubleshooting
+
+| Problem | Fix |
+|---|---|
+| `Failed to set the AnyDesk password` | Make sure the service is running: `sudo systemctl status anydesk`. Then retry. |
+| AnyDesk ID shows as unavailable | The service may still be starting. Run `anydesk --get-id` after a few seconds. |
+| Can't connect / black screen | Check you are on an X11 session, not Wayland. At the login screen, select the Cinnamon (X11) session. |
+| Repo or key download fails | Check network and proxy settings, and that `keys.anydesk.com` and `deb.anydesk.com` are reachable. |
+
+## Uninstalling
+
+```bash
+sudo systemctl disable --now anydesk
+sudo apt-get remove --purge -y anydesk
+sudo rm -f /etc/apt/sources.list.d/anydesk-stable.list /etc/apt/keyrings/anydesk.gpg
+sudo apt-get update
+```
