Description

I'm updating my POC app from beta.2 to beta.4. It looks like the account object that is persisted for a session is much more limited than before and doesn't include the id token claims. My app needs access to the id token claims so this change impacts my app initialization - if I'm getting a fresh session from the server I'll get the id token claims and proceed as usual, but, if I'm initializing with an existing session I don't have access to this data now so my question is - what is the recommended way to get id token claims for an existing session?

Currently I'm working around this by getting the id token data from a subsequent access token request but I'd prefer a solution that's not coupled to other operations. From a performance perspective I'd actually prefer if the claims could be returned from a cache so that we don't incur a new delay to fetch id tokens when we're initializing an existing session.

@deasems You can do this by calling acquireTokenSilent() with openid and profile as the scopes and passing the account object. This will retrieve the relevant token from the cache and contain the idTokenClaims in the response.

Thanks @pkanher617, I tried this out and it worked well 👍
