As a Learner, there are a few steps you can try before intervention from management is required.
First, check where you're logging in to
Make sure it is the proper place you have been directed to log in. If you're trying to sign in somewhere else, your credentials either won't work, or you're signing into something separate from this system.
If your credentials aren't recognized at the correct login page
Select the Reset your Password prompt at the bottom of the login page. This will give you the opportunity to submit the Username you're attempting to sign in with.
If, at the end of the recovery process, you have not received a reset code
Check your junk/spam folders, and also if you have a mobile number on file, check your SMS messages. If you have not received anything inside of a few minutes, your account is likely affected by at least one of these three scenarios:
1) the username you attempted to recover does not exist
2) the username you attempted to recover is expired/not active (and therefore not authorized to sign in)
3) your account password recovery questions have not been filled out yet
For all three of these scenarios, you will require management intervention.
The best way to proceed is to provide the username you attempted to recover a password for, and the email you believe to be associated with the account. If your account exists, but is inactive, your account can likely be re-activated by management. If your account does not exist, it can likely be created for you, and you be emailed a temporary password. Upon login, you will be prompted to fill out password recovery questions, and a new secure password.
