Just got my first Raspberry and don't have a spare keyboard around. I was hoping there would be a key pallet utility to use for my password but can't find one. Help!
You can SSH from another computer and use the command line to configure your WiFi. You can also temporarily use a keyboard to make the settings then return it to the other computer.– Steve RobillardOct 4, 2016 at 23:52
There isn't an onscreen keyboard installed by default on Raspbian, so your choices are (in ascending order of hassle):
Borrow a keyboard from another computer
SSH or console cable into the Pi and change the password on the console (needs a bit of Googling if you don't know how)
SSH or console cable into the Pi and install the onscreen keyboard, then put it in on the graphical mode
