If you're one of the lucky few who has access to Secret Conversations now (you'll know if you are determining the beta testers was an active opt-in process, not a random selection), open up Messenger on an Android or iOS device.

'No secure way to verify code or store keys without routing through mobile.' 'Hundreds of millions use Messenger from a web browser,' Stamos tweeted. On Twitter today (July 8), Facebook Chief Security Office Alex Stamos downplayed the possibility of getting Secret Conversations to work on the desktop version of Messenger. Furthermore, Secret Conversations work only between two participants it's not feasible to offer end-to-end encryption options for a whole group.įinally, the option is available only on iOS and Android devices at present. Encrypting text is hard enough encrypting GIFs, videos, online payments and other 'rich content' won't be possible, at least not at first. On the other hand, end-to-end encryption also comes with a number of drawbacks. Users can already delete regular Facebook Messenger conversations, although it's a bit of a process and only works if both participants take active steps.

Users can also set messages to 'self-destruct,' or automatically erase themselves from both devices after a set period of time. Facebook said to TechCrunch that users probably don't need Secret Conversations for every bit of ephemera, but they could be a crucial extra layer of security when discussing sensitive matters such as Social Security numbers, banking information or personal medical issues.
