Todennuspalvelujen
Todennuspalvelut, also known as authentication services, are systems or processes that verify the identity of a user, device, or system attempting to access a resource. This verification is crucial for security, ensuring that only authorized entities can access sensitive information or perform specific actions. Authentication can be achieved through various methods, commonly categorized into three factors: something the user knows (like a password or PIN), something the user has (like a security token or smartphone), or something the user is (like a fingerprint or facial scan). Multi-factor authentication (MFA) combines two or more of these factors, significantly enhancing security by making it more difficult for unauthorized individuals to gain access.
These services are fundamental to modern digital infrastructure, protecting everything from individual user accounts on websites
