If you are having issues accessing LOIS - even after you have changed your password - are you (or your device) capitalizing the first letter of your username? LOIS is very sensitive and sees the incorrect case as a different username. Enter your username with all lower-case letters.
The username for LOIS is the firstname.lastname@example.org format.
Try using a different browser to log in. However, do not use Safari since that browser doesn't work well with the LOIS login.
If you still can't access LOIS, then please take a screenshot of any error message that you are receiving, and send it to email@example.com. Make sure that you include your name, Lesley username, and student ID number if possible.
