Screens can interact with macOS Screen Sharing's "lock screen" feature, which allows you to conceal the remote desktop for privacy purposes. When using this feature, keep these points in mind.
If the lock screen is active at the time Screens establishes the connection, Screens cannot disable it. This is a macOS security measure, and applies universally to any application. You can, however, work around this by disabling the log-in password requirement:
- macOS System Preferences > Security > General > Require Password
or by activating Automatic Login:
- macOS System Preferences > Users > Login Options > Turn On Automatic Login
These, however, may not be ideal, depending on your security concerns/policies, so weight these options carefully.
