Authentication
Authentication is the process of verifying who someone is when they try to access a computer system or application. Think of it like checking ID at the entrance of a building. It's a fundamental security measure that ensures only authorized people can access sensitive information or systems. This typically involves usernames and passwords, but can also include things like fingerprint scans or face recognition. When you see this term in resumes or job descriptions, it usually refers to the person's experience in setting up, managing, or improving these security checkpoints for companies.
