Now that I more often come to the computer with the baby in my arms, it was always very difficult to put in the password, because I need both hands for it. It's complicated and long and I only can put it in blindly with finger muscle memory.
This is when I remembered that my XPS 13 has a finger print reader. So I set it up now and I'm finally able to unlock it with one hand, and than with this one hand I can use the mouse also :D
