Did Lithium Support Two factor authentication in the Community? If so is there any OOTB component available.
It will be great can anyone provide authentication flow in the Community.
At this current time we do not support or have 2FA OOTB.
However that is a great idea, I did take a look at our idea exchange and I am not able to find any suggestions already around community and 2FA.
I would recommend to file a product idea on the community with your business use case.
