i downloaded the mobile Authenticator for the IPhone and used it successfully for several weeks, and then today it stopped being required for logging in to my account. i unlinked the authenticator app and relinked it, but it still wasn’t working. i deleted the app and relinked my account to my mobile authenticator but it still isn’t asking me for the six-digit code after i log in. is this a change in account security parameters or is it a bug?
many thanks
