Great article. PGP has been around for the last 15+ years and it's stood the test of time IF you create a 4k and above key pair. Pointless creating anything less than that.
Do NOT use KYC protocol as it'll sound the end of Steemit for anyone who gives a shit about their digital privacy and decentralised platforms.
PGP works as a 2fa for login, can be implemented and creates locally using the android APK app and will be around long after all other fancy web based encryption methods have fallen.
