Your username is your gnumber@ wilmslowhigh.com (e.g. G97865@wilmslowhigh.com)

I can't log in - why?
Your password may have expired in school (try logging on at school to check)
Ask a teacher or ISS (room 127) to reset your password (make sure you set a new password in school before trying again at home).
Someone else could have logged into firefly on the same computer
If someone else in your family has accessed firefly (or an office 365 account) your internet browser may have remembered their details. You can try using a different browser (e.g. Chrome, Safari, Internet Explorer, Firefox) or you can try to clear the cache on your browser.
I've tried both of these
Please contact ISS in room 127 at school.
