A dormant account is an identity which exists, but has not been used for a period of time. The period of time required to quality an account as dormant may vary. For example, as you may only login to the DMV twice a year at most, the DMV could define a dormant account being “an account that hasn’t been logged into for more than a year.”
A free email provider may consider a user has abandoned their service, and may cancel their free email account if it hasn’t been logged into for a shorter period of dormancy, for example, six months.
