Speech-Activated Password Resets
This is a clever idea from Microsoft.
We know that people forget their passwords all the time, and I’ve already written about how secret questions as a backup password are a bad idea. Here’s a system where a voiceprint acts as a backup password. It’s a biometric password, which makes it good. Presumably the system prompts the user as to what to say, so the user can’t forget his voice password. And it’s hard to hack. (Yes, it’s possible to hack. But so is the password.)
But the real beauty of this system is that it doesn’t require a customer support person to deal with the user. I’ve seen statistics showing that 25% of all help desk calls are by people who forget their password, they cost something like $20 a call, and they take an average of 10 minutes. A system like this provides good security and saves money.
