It's basically a way to keep your password out of plain sight, to ensure it's pretty much safe. You have no reason to worry about that. A good tip would be to copy & paste the password into that password (asterix) field in order to make sure it's correctly put. This is also good if you use complex passwords like I do.
Then simply clear that field completely and type in your password again. That will make sure you typed it correctly or should have at least made it 100% correct, else you're a poor typer and probably have to take some lessons in writing with a keyboard or similar classes at school or the likes.
