So, I have a Threema license, but from what I’ve seen its encryption isn’t post-quantum. Signal’s encryption seems the strongest. I host my own matrix server.
Also, I kind of don’t care where the servers are or which provider it is. Everything is encrypted anyway.
It’s an issue.
You can’t create an account on desktop. You can’t create multiple accounts. You can’t create an account at all if you don’t have a phone number. You can’t create an account if your phone number’s previous owner created an account. Signal can be subpoenaed for your phone number.
Is it possible to use a number different to the one on the device you use? Seems like a simple workaround to use a throwaway SIM to set up, and then use it with that number moving forwards.
That sounds like an awful lot of work to workaround a problem that shouldn’t have existed in the first place.
Yes: mine uses a Google Voice number.
