Not sure how many good folk here may use two factor authentication. I never did, honestly, until I began getting involved in cryptocurrencies. However, after beginning to use 2fa, I realized just how unsafe many of my online accounts actually were. Security is definitely something I appreciate, especially concerning online access of certain accounts. I'm pretty sure most of you folks feel the same way. Originally, it was recommended to me to use "Google Authenticator". (You will typically see GA used as an example where 2fa is mentioned.) I have since learned of a product that is far superior to Google's application. It's called "Authy". While I am no guru, this program seems to be the cat's meow. I use desktops much more often than my cell phone or tablets here. Truly, I am much happier having this option available on multiple devices. Honestly, there is just no comparison between Authy and Google Authenticator.
