Authentication Protocol

An authentication protocol is a set of rules or procedures used to verify someone's identity when they access a system or service, like a website or app. Think of it as a security check that ensures you are who you say you are. This process often involves entering a password, using biometric data like a fingerprint, or receiving a code on your phone. The goal is to prevent unauthorized access and protect sensitive information by making sure only the right people can enter or use a system.
