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
