 In this scenario, we walk through the case when we have a single-page app (SPA), using MSAL.js to call a Conditional Access protected web API. This is a simple architecture but has some nuances that need to be taken into account when developing around Conditional Access.
 
-In MSAL.js, there are a few functions that obtain tokens: `login()`, `acquireToken(...)`, `acquireTokenPopup(…)`, and `acquireTokenRedirect(…)`.
+In MSAL.js, there are a few functions that obtain tokens: `loginPopup()`, `acquireTokenSilent(...)`, `acquireTokenPopup(…)`, and `acquireTokenRedirect(…)`.
 
-* `login()` obtains an ID token through an interactive sign-in request but does not obtain access tokens for any service (including a Conditional Access protected web API).
-* `acquireToken(…)` can then be used to silently obtain an access token meaning it does not show UI in any circumstance.

 * `acquireTokenPopup(…)` and `acquireTokenRedirect(…)` are both used to interactively request a token for a resource meaning they always show sign-in UI.
 
-When an app needs an access token to call a Web API, it attempts an `acquireToken(…)`. If the token session is expired or we need to comply with a Conditional Access policy, then the *acquireToken* function fails and the app uses `acquireTokenPopup()` or `acquireTokenRedirect()`.

-Let's walk through an example with our Conditional Access scenario. The end user just landed on the site and doesn’t have a session. We perform a `login()` call, get an ID token without multi-factor authentication. Then the user hits a button that requires the app to request data from a web API. The app tries to do an `acquireToken()` call but fails since the user has not performed multi-factor authentication yet and needs to comply with the Conditional Access policy.
