Screens supports three different URL schemes. All three will prompt for a username and a password, if they are required and not specified in the URL. Screens complies with the RFC 2396 URL schemes specification.
SCREENS://
Use the screens:// prefix to open a saved screen.
Usage:
screens://[ip address|hostname|name]
Examples:
screens://10.0.1.10
screens://Johns-MacBook-Pro.local
screens://John's MacBook Pro
screens://john:sekret@John's MacBook Pro
VNC://
Use the vnc:// prefix to connect to a computer not included in your saved "screens" list.
Usage:
vnc://[username:password@]address|hostname[:port]
Examples:
vnc://10.0.1.10
vnc://10.0.1.10:5900
vnc://john@Johns-MacBook-Pro.local
vnc://john:sekret@Johns-MacBook-Pro.local
vnc://bill@192.168.1.14:5801
Note 1: if no username or password is present in the URL, Screens will assume that the authentication method is VNC password. It is recommended to add a username (with or without a password) in the URL when connecting to a Mac as Screens will then use Mac User as the authentication method.
Note 2: Screens treats both vnc:// and screens:// equivalently on macOS.
SSH://
The ssh:// prefix requires the same parameters as the vnc:// prefix, but establishes a secure network connection for your Screens session.
Usage:
ssh://[username:password@]address|hostname[:port]
Examples:
ssh://10.0.1.10
ssh://10.0.1.10:22
ssh://john@Johns-MacBook-Pro.local
ssh://john:sekret@Johns-MacBook-Pro.local
ssh://bill@192.168.1.14:222
macOS Support
On macOS, it is possible that URL schemes vnc:// and ssh:// may be reserved by the operating system. In those cases, it is recommended to use the Open Link functionality (File > Open Link... or ⌘O) in Screens instead of clicking on a link, which may open another system application instead.
