Authentication is basically how a system makes sure you are really who you say you are. For example, when you log into your bank’s app with your username and
password, or even your fingerprint, the system checks that information against what it has on file (Microsoft, 2023). Authorization comes right after that, deciding what you’re
allowed to do once you’re logged in (IBM, 2022). Using the same bank example, you might only be able to see your own account details, while a bank employee with special access could view multiple customer accounts.
