The first run takes three steps: install and sign in on the computer you want to reach, install and sign in on the device you will use, then click Desktop control.
Prepare the host
Install Sunlogin on the target computer and sign in. The device appears in your account device list and shows as online.
- Install the client and sign in
- Confirm the device shows as online
- Give it a recognisable name
- Enable start-on-boot for long-term availability
Start a session
Open the device list on the controlling side, tap the device and choose Desktop control. Without unattended access the host shows a prompt that must be accepted.
- Select device then Desktop control
- Accept on the host or enter the access code
- Switch quality or go full screen
- Click disconnect when done
After the first session
Three things make every later session smoother: set an access code, enable unattended access, and test one file transfer.
- Set an access code and enable unattended access
- Test that file transfer works
- Tune quality and resolution to taste
- Sign in on your phone as a backup
FAQ
Do both devices need the same network?
No. Any internet connection works. The same LAN usually gives lower latency; across networks traffic relays through encrypted servers.
Can one account sign in on two computers?
Yes. Multiple devices can share an account and see the same device list, which makes mutual control easy.
