Sikkerhetsnøkkelbasert

Sikkerhetsnøkkelbasert refers to a method of authentication or authorization that relies on the use of security keys. These keys are typically physical devices, such as USB drives, that store cryptographic information used to verify a user's identity or grant access to a system or service. The underlying principle is that possession of the physical key, combined with other factors like a password or biometric data, provides a stronger form of security than password-only authentication.

This approach is often implemented through protocols like FIDO (Fast IDentity Online), which aims to standardize secure and user-friendly authentication methods. Security keys can be used for logging into websites, applications, and even operating systems. They are designed to be resistant to phishing attacks, as the cryptographic material on the key is not directly transmitted over the network in a way that can be intercepted and reused by malicious actors.

The use of sikkerhetsnøkkelbasert authentication offers several advantages, including enhanced security against credential theft and simplified login processes for users who do not need to remember complex passwords. However, it also introduces considerations related to the physical security of the keys themselves and the potential for loss or damage. Implementing this method typically involves a registration process where the security key is associated with a user account.
