Login user - opposite to launchctl bootout user/id

Question

How can I login user in programmatically way?

I need something opposite to command

launchctl bootout user/502

that logouts user with id=502.

Does this way exist?

Answer 1

Not on macOS

No, there is no Apple supported programmatic way of logging in a user on macOS.

One approach would be to create a virtual smart card and simulate a user logging in. This would require significant effort and development time.
