If you are trying to login to the Micro Course, it is possible your course has expired and your email is no longer in our system. This means we need to sign you up again. Here is the link to do that https://www.boldschool.com/offers/hXLSeogw/checkout. Just sign in with the original email you registered with, and the system should allow you to chose a new password at the same time. Please let our Support desk know if you have further difficulties.
The rest password is good for six hours. Beyond that, it is also possible that the reset password has simply expired. You will need a new password link. When you ask for a password reset link, remember to keep checking your inbox so that it does not expire again. Good luck!
