Avoid using the "remember password" functionality. Do NOT select options like "Remember me" or "Keep me signed in".
Sign in on device
Always sign out completely from the (Windows) machine if you used a shared or public computer at Ghent University.
Sign in to sites and applications (in browser)
Always sign off from UGent sites and applications which you used, like the portal site (intranet), Minerva and Athena. It is important that you click the "Log off" or "Logout" link.
Closing the browser window is not enough to keep someone from using your username and password. You can still be signed in, after you close your browser. A browser can be set to store passwords without warning. You can verify this very easily: after logging off and closing the browser, you restart the browser and surf to the same page. The password should not be entered.
If the password is filled out, you must remove the stored password.
You do well to turn off password saving.
