What should a student do if they suspect they've signed into a fraudulent site?

Changing the password is the most crucial and immediate action a student should take upon suspecting they have signed into a fraudulent site. This helps to secure their account by preventing unauthorized access. If the site is indeed fraudulent, it’s likely that their login credentials could be compromised, so updating the password ensures that even if someone has gained access, they cannot continue to use it.

In addition to changing the password, it is also advisable for the student to consider enabling two-factor authentication for added security and to monitor their accounts for any unusual activity. While contacting tech support can also be important, especially if there are other technical issues or concerns, the first step should always be to secure personal accounts through password changes. Informing friends about potential fraud does not directly protect the student's own information, nor is ignoring the situation a responsible approach.
