When a user is created in Litmos and sent the login email, they will receive an email with a link that allows them to login for the first time and update their user profile information including choosing their new password to access the Litmos system. This login link is formatted using your unique Litmos website address followed by //login.aspx?loginkey= and a series of letters, numbers and dashes.

Once a learner has used this login link, this link will expire.  This is to keep the user from sharing the link and giving other users access to Litmos:

After users have used this login link, they need to login to Litmos using the  login page which is the Litmos URL defined by an Account Owner in Account Settings > Profile > Custom website address.
