Proton Mail now supports post-quantum encryption, helping protect new encrypted emails against future quantum threats.

It seems that I can set it from the Android app, not from the web interface.
Does anybody know what the (potential) repercussions are of enabling PQC? I would hate it if I lost access to some emails this way.
edit: see this message. The feature is temporarily disabled as some users of Proton Drive for Windows (Tux is still crying…) reported issues with sync after enabling PQC. PQC only applies to new encrypted emails going forward.
Can someone explain what the point is when the email contents are all read by the sender? Everything is already in a database somewhere.
Well, if the other person uses protonmail, your client encrypts the email content before submitting it, which means protonmail can’t read it.
If they do not use protonmail, well, protonmail can. They apparently store the emails after they have been sent encrypted with a key in your account, so they can’t read them afterwards.
About 99% of the world doesn’t use protonmail. What good does it do if your email is stored unecryptes in the recipient’s imbox over on gmail, apple mail, copilot 360, yahoo, yandex, or whatever else?
I can encrypt a message with your public key, and only you can decrypt it. The db will store the encrypted version.
For example.
This is not necessarily what/why they do it, just one example of how asymmetric ciphers can be useful in an email scenario.
