Authentication is the process of determining the user’s identity via credentials. Example:

• Authenticate through Usernames and passwords
• OTPs are another way to get access to the system for a single transaction
• Biometrics such as an eye scan or fingerprints can be used to gain access

Authorization, on the other hand, occurs after your identity is successfully authenticated by the system, which ultimately gives you full permission to access the resources such as information, files, databases, funds, locations, almost anything.
