todennusvaihtoehtojen refers to authentication options. This term describes the various methods and mechanisms that can be employed to verify the identity of a user or system attempting to access a resource or service. The primary goal of authentication is to ensure that only authorized individuals or entities gain access, thereby protecting sensitive data and systems from unauthorized use.

Common authentication options include password-based authentication, where users provide a secret password. Multi-factor authentication (MFA) is another prevalent method, requiring users to present two or more pieces of evidence to verify their identity, such as something they know (password), something they have (a physical token or smartphone), or something they are (biometric data like a fingerprint or facial scan). Biometric authentication, which uses unique biological characteristics, is increasingly integrated into modern authentication systems.

Other options include token-based authentication, often used in web applications, where a token is issued after successful login and subsequent requests include this token for verification. Single Sign-On (SSO) solutions allow users to log in once with a single set of credentials to access multiple independent applications. Certificate-based authentication uses digital certificates to verify identity, often employed in enterprise environments.
