Proton Mail now supports post-quantum encryption. While quantum computers can’t break today’s encryption yet, preparing early matters. Data encrypted today could be targeted in the future. With this update, you can enable post-quantum protection for new encrypted emails, on any plan, including free. Learn more: https://proton.me/blog/introducing-post-quantum-encryption

@protonprivacy The activation popup says it doesn't work with "old app versions", so, which app version is needed? So I don't accidentally activate it before the update is available to me. 😅
