alt Hacker NewsThe option was there in Cyanogenmod back during the OnePlus One days. It was such a step backwards when it was removed. You almost had to wonder if it was deliberately done at the request of some TLA to prevent users from using too strong of a password for decryption.
I doubt it, mostly because phones were a lot easier to crack back in those days already so I doubt a TLA needed to push for it to be removed.
