Overview#Bring Your Own Identity (BYOI) is an approach to authentication in which an end user's username, password and other Digital Identity attributes is managed by a Third-party Identity Provider.
Bring Your Own Identity is being driven by users’ "identity fatigue". Users have too many accounts, too many usernames and too many passwords. That makes the mere step of registering at a new site one anathema too many. When the competition is literally a click away, organizations must enable the easiest user experience possible or users migrate to sites that offer the simplest registration and login process.
