getFirebaseAuth

public abstract @NonNull FirebaseAuth getFirebaseAuth()

Returns the FirebaseAuth reference for the current MultiFactorResolver.

public abstract @NonNull List<MultiFactorInfo> getHints()

Returns a list of MultiFactorInfo which represents the available second factors that can be used to complete the sign-in for the current session.

getSession

public abstract @NonNull MultiFactorSession getSession()

Returns a MultiFactorSession, an opaque session identifier for the current sign-in flow.

This is needed to be provided with the second factor. It will provide context to the Auth backend on the first factor user to sign-in.
