Which library is commonly used to cache tokens after acquisition in authentication flows?

• A. MSAL
• B. OAuthlib
• C. OpenID Connect
• D. JWT

Answer: (A)

Caching tokens after acquisition is all about storing the tokens you’ve received so you can reuse them for future requests without having to re-authenticate each time. MSAL is the library built for this purpose. It not only handles the authentication flows but also manages a token cache that stores access tokens, refresh tokens, and ID tokens. With MSAL, you can acquire a token silently by checking the cache first and only prompt the user when necessary, which keeps apps responsive and reduces login prompts. It’s designed to work across platforms and with Microsoft identity providers, while also fitting into OpenID Connect flows. The other options aren’t aimed at providing a built-in token caching mechanism. OAuthlib implements OAuth protocol flows but doesn’t standardize a persistent token cache across sessions. OpenID Connect is a protocol layer for identity on top of OAuth 2.0 rather than a caching library. JWT is simply a token format used within many auth systems, not a library that manages or caches tokens.
