@Likethebird -
There could be a couple of reasons. First, is the password saved on your phone such that you do not have to enter it to get onto Canvas? If so, is it possible that the password used by your phone is different from what you are trying to use on the computer? The other issue would be using the correct username (i.e. you did not swap the order of 2 letters in the username). Or make sure caps locks is off. Or if you have numbers and you use the numeric keypad is the numlock key on.
