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!
