Messages and files shared through Teams are encrypted the moment they are sent and remain encrypted when they are received.

Some professional users are probably familiar with Keybase , a tool for creating a secure online identity and sending private messages to others. Today, the company responsible for this tool has launched Teams , an end-to-end encrypted group chat application that looks a lot like Slack.

The service, developed by the creators of OkCupid and SparkNotes, is currently in alpha version , is completely free and promises to keep the conversations hidden from prying eyes, even if the company’s servers are hacked. This is because messages and files shared through Teams are encrypted the moment they are sent and remain encrypted when they are received.

To use Teams, you need to have the Keybase application installed , which is available for Chrome, Firefox, Android, iOS, MacOS, Linux and Windows, reports TNW .

Keybase Teams is free for the time being, although the company acknowledged that it will likely start charging companies for its use at some point. Its clear focus on security could make this tool more attractive to some customers than rival applications such as Slack, Microsoft Teams, Flock, Facebook Workplace and Atlassian’s new Stride product .

Keybase ensures that Teams is designed to work well for both large and small businesses, as well as for user and developer communities. At present, a Teams team can support up to 1,000 people , although that limitation will be eliminated later. The company is also working on a coded code repository so programmers can share their work in the most secure way.

Of course, it will not be a one-day thing to come face-to-face with your mighty rivals. Slack has more than 5 million users, while Microsoft and Facebook products have the power of these large companies to maintain their options in the market for enterprise messaging services.
