I’m currently running Grapheme OS on a pixel. One thing that I’ve had trouble finding is a secure video chat option. I’m assuming that its because such a thing in a secure environment is hard to come by / impossible.
The only options I’ve found are things where you must self host like element etc. Is this the only way?
I realize there may be nuanced answers to this question that I may be overlooking as I’m still relatively new to online security/privacy so I apologize in advance if this is a moot question.
I’d argue SimpleX does it better, they’re even modifying the Signal protocol to support post-quantum encryption. No phone number, uses the Signal protocol, and has no user identifiers at all (no usernames, no account numbers, no account at all; everything is stored locally on your device).
Oh also, before the reply that Signal is post-quantum already, here’s an excerpt from the blog post I linked detailing why SimpleX’s implementation is better:
unlike Signal design that only added quantum resistance to the initial key exchange by replacing X3DH key agreement scheme with post-quantum PQXDH, but did not improve Signal algorithm itself, our design added quantum-resistant key agreements inside double algorithm, making its break-in recovery property also quantum resistant.
There is much more detail in the blog post if you’re interested. SimpleX also has an incredible whitepaper

Signal is pretty good all around and phenomenal considering that it’s free.
signal 1-1 encrypted video chat
signal encrypted group video chat
Hard to beat Signal for getting all the core elements of secure chat.
