The default FOSSEE Laptop password for 'student' login is 'student'(without quotes).
If you changed the password and forgot then you may login as 'root' user and change your 'student' password.

Use Cnt + Alt + f1
Login name: root
Password: student

Then you may run following command:
   passwd student
