We have had a question and answer feature in IPS Community Suite for some time and we are now happy to add Google Authenticator as another option. We have also combined the various options it a new Two Factor Authentication (2FA) section in the AdminCP with many more options.

Two Factor Authentication Settings
There are also new settings to control when a user is required (or not) to setup 2FA:

2FA Setup
You can control what areas will prompt for 2FA authentication:

And how the system should recover if a user cannot login via 2FA on their account:

2FA Recovery Settings
An administrator can configure these settings to tailor the security needs of their community. For example, you might want to require 2FA your admins and moderators but keep it optional for your members. 
On the front end your members will see a new Account Security section under their settings area.

Once authenticated, a user will then be able to enable various security options. For example, the Google Authenticator setup shows an easy to follow setup.

We hope you enjoy this new level of system security. IPS has plans to add additional 2FA providers beyond Question and Answers and Google Authenticator. We will keep you updated!
 
This change will be in version 4.1.18 which is scheduled to be released in late January 2017.

Last week we introduced you to a couple of key new improvements in IPS Community Suite 4.1.12, the new post preview and enhanced activity streams and search. However, this is a packed release, so I wanted to quickly review what else you can expect to find when it is released this week.
Mentions
4.0 introduced mentions, and since then a frequently-requested feature is the ability to ignore notifications triggered by particular members. In 4.1.12, we enhanced the Ignore Users functionality to also allow you to block mention notifications. They will still be able to mention you in posts, but you will no longer be notified about it.

Ratings
As of 4.1.12, ratings will now display half-stars in order to be more accurate. Users will still rate whole stars out of 5 (or 10 if configured so), but the aggregated ratings displayed alongside content will be more fine-grained.
Custom date formatting
We have used built-in, automatic locale formats for dates since 4.0, but it became increasingly clear that this did not offer the flexibility that some community administrators desired. As a result, 4.1.12 re-introduces the ability to provide custom formats for dates.
Bug fixes
Amongst the handful of new features, there's over 400 other bug fixes and improvements that contribute towards the overall stability of the IPS Community Suite, as we start working towards the next major release, IPS Community Suite 4.2 which will be available later this year. Further fixes for stability in the 4.1 line will come before 4.2 is available.
