Get the status of the current MFA session.
Note: You can get the status only for an MFA session where rememberMe is set as true in /MFAAuthenticate.json.
In the response, if isTrusted is false, the MFA session is no longer trusted. At that point, you must follow the three-step process again and sign in with an MFA trusted API session.
