Identity management

Identity management is a way to keep track of who people are so that only the right people can get access to the right things. When you log in to an account with a username and password, that's a type of identity management because it helps the account know that you are who you say you are. Whenever you log in somewhere, your identity is checked and you can be given access or denied. This helps keep everyone safe and secure.
