[Sticky] Two-factor authentication (also known as 2FA)  

Two-factor authentication is available on weirdknight.com. Two-factor authentication (2FA) adds an additional layer of protection beyond passwords.

• Enable 2FA using any standard TOTP + HOTP protocols (and so supports Authy, Duo, Google Authenticator and many others).

• A graphical QR code is available  for easy scanning and setup into apps on your phone/tablet accessed through ACCOUNT DETAILS.
