That's true. You could end up with bad Opsec and then accidentally download both Signal and Telegram on the same device, reducing (but not eliminating) security

That's true. You could end up with bad Opsec and then accidentally download both Signal and Telegram on the same device, reducing (but not eliminating) security. Thanks I'll add this to vulnerabilities. You can mitigate that with some upfront choices. For example, use a blackberry and blackberry messaging as one device, which wouldn't be available on other devices?
