2 Factor Via SMS or Google Authenticator

[shadowcodex]

I’m interested in adding 2FA to a meteor app I am about to build. I saw this post on the same topic:

Is there anything that does two-factor or multi-factor authentication for Meteor?

I’ve found one article laying out how to do two-factor authentication in Meteor with Twilio SMS. I like this as a solution, but I can’t get over the fact that I’d be writing my own security for two-factor authentication. Anyone know of an existing package?

However this seems to have gone the route of Oauth. I am only interested in adding 2FA to the current meteor accounts package. I want to do something either with Twilo or Google Authenticator.

Are there any packages out there that handle this already and seamlessly?

Thanks a bunch!
