How can I log into both the SteamClient session and the MobileApp session with a single login attempt (username + password + SteamGuard mobile code just once)?

[udoless]

The features I’m using require different types of sessions.
For example, enableTwoFactor needs a MobileApp session, while component-related operations like getCasketContents require a SteamClient session.

Is there a way to obtain both sessions with one login process (one username/password + one mobile authenticator confirmation)?
Or is it possible to convert between these two types of sessions?

No, you'll need to login twice.
