# Lockscreen
|
||||
|
||||
This is a barebones lockscreen with a password input box.
|
||||
Note that you MUST have `pamtester` installed or you won't be able to log in.
|
||||
|
||||
You can run the lockscreen with `quickshell -c shell.qml`.
|
||||
|
||||
You can run the lockscreen in test mode (as a window) with `quickshell -c test.qml`.
