At the ongoing Google conference, the company introduced a new chat app called Allo. The app has incognito mode that has complete end-to-end encryption just as much as the next best chat app on the market right now. The technology that is behind that security is far much common.

Shortly after the launch of the new app, Open Whisper Systems also announced that they had been working on the development of the incognito mode for the Allo chat app. The resulting feature was to be written on the company’s Signal protocol.

The company wrote in a blog post that, “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.” They also went on further to note that they would reveal any new technical details and also provide a summary of the app when it was launched.

The protocol from the company is open sourced and has been used in many chat apps for security already. The most popular chat service with over a billion users, WhatsApp also uses the software and it recently finished putting end-to-end encryption for its users. Open Whisper also has its own chat app called Signal. The Signal Protocol is generally thought to be very secure.

Allo works differently from Signal and WhatsApp. Users have the option to switch from private to public conversation when they want. It has led to some concerns that this might make users send unprotected messages by mistake.
