Long story short, I want to enroll Google Authenticator based two factor login for my laptops. Sadly sddm doesn't support verification codes so I switched to lightdm. Now the problem is, that the lockscreen from Plasma doesn't support two factor login either, resulting in me not being able to unlock my screen.

Can someone give me a guide, a hint or anything that helps to use lightdm as my lockscreen?

Edit: After googeling a bit more I found out that I need to replace kscreenlocker with dm-tool. Does someone know how?
