Google's Allo chat app uses some well-known encryption, but not by default

Google debuted a shiny new chat app called Allo during its IO 2016 conference today, and while it's a fresh take on messaging, one element of the app is actually quite familiar.

Turns out Allo's end-to-end encryption is built on the Signal Protocol, the same standard used to power encryption in WhatsApp and the Signal app.

"We've been collaborating together on the integration of Signal Protocol into Allo, which will bring all of Signal Protocol's strong encryption properties to Allo's incognito mode," wrote Open Whisper Systems, creator of the protocol, in a blog post.

This is worrisome as you might accidentally send a message you wanted encrypted as, well, not encrypted, if you forget to switch to Incognito Mode.

What's more, as noted by TechCrunch, Allo's most helpful features won't be so helpful if it can't see what you're talking about.

Others have argued that opt-in end-to-end encryption at this point is better than none at all, but how many users bite when Allo becomes available later this summer remains to be seen.
