I am adding security feature that allows you to use a 2 Step Verification to sign in to the forum. I am doing this mainly to protect my Admin account from any would be hackers. I will extend the option to regular users in case you would like to use it. You will be able to use Google Authenticator or YubicoYubikey apps to get your keys. I only use the Google app so I won't be testing it on the Yubico app.
No action is required if you do not wish to use this feature.
If you don't know what it is here is short description by Google: Google 2-Step Verification
I'll add quick guide on how to set it up once I have everything in place.
