Quick start

  1. Deploy from the Azure Marketplace (Get It Now → Create), choosing your SSH key at the Administration step.
  2. Allow inbound SSH (22) for yourself plus the application port(s): 8384 (web GUI) to your IP; 22000 tcp/udp to your peers — restrict to your own IP where possible. The in-image firewall already allows them; only the Network Security Group (NSG) keeps them closed.
  3. Open http://<VM-IP>:8384/ and sign in as syncthingadmin (see First login below).
  4. Add your other devices (Remote Devices → Add) using their Device IDs and share a folder.

First login / credentials

This image generates its admin credential on the VM at first boot — nothing is pre-set. SSH into the VM with the username + key you chose at deploy, then print the generated credential:

ssh <your-username>@<VM-IP>
sudo cat /root/syncthing-admin-credentials.txt

Sign in as syncthingadmin.

  1. Print the credential file: username syncthingadmin, the generated GUI password, and this VM's Device ID.
  2. Open http://<VM-IP>:8384/ and sign in.
  3. Rotate the GUI password (Actions → Settings → GUI) and enable HTTPS for the GUI before real use; add remote devices by their Device ID and share folders.

Sign in as admin (unless noted), then change the password immediately. The file is root-only and can be deleted once the password is stored securely.
