There is no built-in method of doing this on the LMS, however, the administrator who originally enrolled the learner will have a copy of the login details sent to them by email which they could forward onto the learner manually. The learner will also need to know where to login, so a link to the access portal https://lms.highfieldelearning.com/ should also be provided.

Learners should be able to log in using these details.

A unique link is not required. Both learners and administrators should be able to access the portal. 

If you are an administrator, but not the one that created the learner account, you are still able to reset the learner’s password and provide the learners with their login credentials. Instructions on how to do this can be found here: Learner Support - How do I change a learner's password?
