Craftster user Omega Chicken made this sampler as a simple way to remember her WiFi password:
My housemate got the idea from when friends come over with laptops and mobile devices and always need to connect to her wifi. It was a hassle looking at the router every time and she doesn't know how to change the password to something memorable and whenever she wrote it down on something, it'd get lost. So here it is to be framed and hung on the wall.
