As the customer I should be able to decide what security I need based on my threat model not what Proton thinks it knows about me and my threat model. I signed up for Duo and find the iOS Mail map doesn't work because Proton doesn't supply IMAP/SMTP over TLS which eliminates 99% of the threat. I am leaving companies that decide to solve things in a proprietary way without industry standard options.
