Sessionsextended

Sessionsextended is a concept in web and application security describing methods to extend the active authenticated session of a user beyond a standard expiration period while balancing security.

Common approaches include sliding sessions (extend on each request during active use) and token-based refresh where a short-lived access token is renewed using a long-lived refresh token.

Implementation often involves a server-side session store paired with client-side tokens stored in cookies or local storage. Security best practices emphasize HttpOnly and Secure cookie flags, SameSite restrictions, and token rotation to limit exposure.

Use cases include enterprise dashboards, SaaS platforms, and mobile apps where frequent reauthentication would hinder productivity.

Security considerations include the risk of token theft, requiring measures such as device binding, anomaly detection, MFA for refresh, revocation mechanisms, and centralized monitoring.

There is no universal standard named sessionsextended, and implementations vary across frameworks; the term describes a family of techniques rather than a single protocol.

Related concepts include session management, sliding expiration, refresh tokens, and token-based authentication used in OAuth 2.0 and OpenID Connect.
