Authentication

Definition

The process of proving identity to access a system.

In Plain English

Authentication is like showing ID at the door—proving you are who you claim to be.

Real-World Example

API authentication might use an API key, username/password, or OAuth tokens to verify requests.

Why It Matters for Your Work

Authentication protects data and ensures only authorized systems can access your APIs.

Common Mistake

Sharing API keys publicly. Treat API keys like passwords—keep them secret.

Related Terms

API

A way for software systems to communicate and share data with each other.

OAuth

A standard for granting applications limited access without sharing passwords.

MFA

Multi-Factor Authentication—requiring multiple proofs of identity to log in.
