[messaging] Peerio

[Andrew Hintz]

Using a password to derive your private key is interesting and makes
for great portability. However I see phishing for passwords as a major
attack vector that is regularly exploited. Perhaps Peerio users will
be less susceptible to phishing due to being used to typing their
password within an app and not on a webpage.

The other drawback people have mentioned is that there's no way to
change your password.
