I was setting up a new email in Thunderbird (android) and Kmail (because the version of Tbird in the Fedora repo is old and doesn’t have the bugfix required for me to add new accts, so I’m stuck until they decide to update it) and I noticed both support something called Autocrypt in the pgp settings. I searched it but got some bullshit about car keys, so I figured maybe someone here would know.
It seems like a useful thing especially for those who claim pgp is too difficult, but I’ve never heard it mentioned once, and so I’m left wondering why that is. Is it secure? Does using it cause interoperability issues with people who don’t use pgp or autocrypt (say some gmail user)? Is there some other drawback I’m too blind to see?
Anyone with any advice or experience using this “Autocrypt” that I didn’t think to ask please chime in as well!


Proton is very clear that e2e is only between Proton accounts. They do have a way to encrypt when going outside the ecosystem, but I haven’t explored it because nobody I know would do it, nor cares about privacy. Even now.
They are not lying at any point but this marketing page don’t make it clear and instead promote an encrypted and secure provider without saying that there is no protection outside of it
I’ll give them a “lesser evils” pass. If they were as pervasive as Gmail then the marketing would be essentially true.
