The biggest red flag to me when trying ProtonMail was that they opt you into password reset via SMS. How could my email be secure if my cell provider (ie, the government) owns the channel for resetting my password?
Resetting your protonmail password doesn’t seem to unencrypt your previous emails.
I lost emails because of this, because after i changed my password, all the emails i had were encrypted. It was my fault, i'm not digging at Protonmail.
