Hello,
@Cryptopia, do you plan to implement a REAL two factor authentication?
If the user have a key-logger or somebody is filming it, the PIN you have is useless, because it's static! I don't feel secure in your site.
There's a ton of 2FA-related stuff in your settings on the site, including Google Authenticator. What's wrong with those?
Thank you.
After your message I've looked in details the Security tab.
It's UI problem. When you setup your account with PIN, then only available option is PIN, until you disable and enable 2FA again, then with Google Auth.
