question

At re:Invent '17, we announced Developer Preview for unique speaker recognition. I'm not sure if speaker recognition will support the security needed for sensitive interactions like financial skills.

You can request access to the Developer Preview here.

I'm thinking Alexa should support voiceprints. If for no reason other than preventing Alexa from disclosing privacy information. Things like my address, list content, accessing contacts, allowing me to purchase things, etc..... I'm thinking this is like right around the corner for all voice based devices Amazon or not - yes? I don't have reason to believe any kind of location based authentication works reliably or that users really want their devices locked to a specific place. Voice seems logical. I can use my device anywhere just like my cell phone but if I'm not the person that owns that device limits are placed on my capabilities. In the case of a cell phone its a fingerprint or pin.
