Less enticing, perhaps, is the thought of using the popular instant messaging app to send personal details such as identification numbers, or financial account information.
Enter Facebook Messenger’s new “Secret Conversations” feature, which the company began testing on a selective basis today.
Based on open-source Open Whisper Systems technology, Secret Conversations allows either participant in a Messenger conversation to request that the conversation be made BlackBerry Messenger-level private, a request both parties must approve (click on the image for a larger version).
Once the option is activated, a private conversation can only be accessed from one device per user – so discussions started on mobile devices cannot be accessed from the desktop version of Messenger, or vice versa – and while conversations are stored on the participating devices, they cannot be accessed by Facebook itself.
Users can also choose to make their messages “disappear,” Snapchat-like, by augmenting the conversation with a timer that deletes each message as its time runs out.
It’s also worth noting that the secret conversations feature does not currently support rich content such as GIFs, videos, payments, or other popular Messenger features, and that users will still have the option to report abuse.
In a July 8 blog post, Facebook emphasized that messages and calls on Messenger already benefit from secure communications channels identical to those used on banking and shopping websites, in addition to Facebook’s own spam and malware-blocking tools.
However, the company acknowledged that users have requested additional safeguards for certain conversations — such as those discussing an illness or health issue, or financial information, and that Secret Conversations was the result.
The feature is only available on a limited test basis right now, but Facebook plans to roll it out during the summer, measuring its performance and gathering feedback along the way.
