Does anyone know how secure Facebook Messenger communication is? If you are having 1x1 chat (writing messages) or making a voice call, is it encrypted (end to end)?

I know if you are using facebook.com for chat, it is on HTTPS and that is secure. My question is related to the Messenger app on Android.


Yes, it is secure. The connection is made using TLS 1.2. This is from a tcpdump capture on my device: (edge-mqtt-shv-01-iad3.facebook.com)  TLSv1.2  Application Data                                       TLSv1.2  Application Data

  • Good information! What'd be your answer I asked the same question for Snapchat? – SarpSTA Mar 25 '16 at 20:28

    @SarpSTA I don't have Snapchat, I'd suggest posting a separate question. – Matthew Read Mar 25 '16 at 20:35
