It might be nicer if you made them say "yes" so that replays could be detected. Pressing 1 makes the same tone every time, so malware on smartphones can easily bypass this authentication method.
- ubernostrum 17y agoIf you're going to be that paranoid, the phone can't do it; the malware could simply record your voice saying "yes" and replay that recording as needed.

- jonknee 17y agoIt's much more difficult to have malware on your computer and on your phone at the same time from the same attacker. But it could be random, do whatever the instructions say (sometimes 1 means yes, sometimes it means no).
