2Factor Authentication

Yes, this would be a nice extension to the core - we use the built-in features in IPS4 and XenForo - would be great to see it coming to the WSC-Core aswell.

Tim Düsterhus used to have this plugin for WCF 2.0/2.1 but unfortunately he has not developed it for the WSC yet.

I think it should be included in the WSC Core and support the suggestion!

Personally, I would be satisfied when it supports two modes. The first one is a simple email verification, like Steam does, and the second one is using an "really" encrypting device, for example, a YubiKey and as a fallback, normal devices like smartphones or tablets.

I'm aware of that plugin, but I would rather have that implemented from WoltLab.

I personally dont care if its official or not, but a 2-Factor-Auth in combination with Google Auth or similiar apps would be great.
I can find plugins for that in vBulleting and in the latest MyBB its already included as core option.

I am not sure why Tim Düsterhus does not state if he wants to convert his plugin for WSC or not

At some point he might say something about it.

I'll mark this as duplicate of this German thread for housekeeping purposes: 2-Step-Verification (E-Mail, Google Authenticator, U2F, OTP, ...)
