Oppfriskingstokener

An oppfriskingstokener, often translated as a "refresh token," is a security credential used in authorization frameworks like OAuth 2.0. Its primary purpose is to obtain new access tokens without requiring the user to re-authenticate with their credentials each time. When a user initially grants an application permission to access their resources, the application receives an access token. This access token has a limited lifespan. When it expires, the oppfriskingstokener can be used to request a new access token.

Oppfriskingstokener are typically long-lived and are stored securely by the client application. They are not sent with every request to access protected resources. Instead, they are sent to an authorization server's token endpoint. The authorization server verifies the oppfriskingstokener and, if valid, issues a new access token, and sometimes a new oppfriskingstokener as well. This mechanism enhances user experience by allowing continuous access to resources without frequent interruptions for re-login. It also improves security by minimizing the exposure of sensitive credentials. Proper handling and secure storage of oppfriskingstokener are crucial to prevent unauthorized access.
