BITTREX SUCK, [...] They require you to have a smartphone and they go absolutely draconian on any customer who refuses to buy a smartphone or use Google's products.
Are there any alternatives to google 2FA?
I mean why do we need to use google software for this?
Is there any software that can achieve 2FA without using any of the google software?!

This fucking exchanges are all pro google!
I do not want to be tracked by them 24/7 ;(
What about the OATH Toolkit (
http://www.nongnu.org/oath-toolkit/index.html)? It's free software (is it from Google?). No need to buy a smartphone for 2FA. This is available for Linux ($ oathtool --totp -b [KEY]). And there's some software for Windows, too. Authy was mentioned before (dunno if this one's from Google).
Still there are these Google captchas we all love.
