PSA: Back up your Google 2FA Codes!

Upvote for Visibility please!Just imagine this very possible scenario. You’ve invested in a coin, and it’s went up 1,000%, you’re all excited. Then when you go home to unload your bags and rake in that profit, you realize you left your phone behind and have lost it. You can no longer enter your exchange account. You then email your exchange, but it’s futile, as it’ll take a minimum of WEEKS before you hear anything. Your coin that went from making 1,000% profit, has just massively dumped, and you’re now at a loss. How does that feel, knowing you could’ve made bank, but instead you forgot to back up your 2FA codes.This is just a heads up guide to those who may not be aware that your 2FA codes matter a ton, especially for most exchanges that could very well take months to get back to you (Bittrex, Coinbase, Binance) on resetting your 2FA code if you should ever lose your phone.Most people will often OVERLOOK the 2FA setup text code that is shown to you when initially setting up your 2FA. They see the barcode and they immediately go to scan it and proceed. When you lose your phone, that 2FA code (in text format, or the barcode itself) will be used to recover your 2FA authentication into your account. You should ALWAYS back up the code or take a screenshot of the barcode and save it somewhere safe, such as an external storage device, like an offline USB, that you could enable Bitlocker on and encrypt, or write the codes down on paper. If anyone gets ahold of your 2FA codes and your login information, your account is as good as gone.Another alternative would be to set up 2FA on a secondary phone as well. It’s not uncommon for people to have more than 1 phone, such as myself. I have a secondary backup phone, that I can use as a secondary 2FA device (that never leaves home and stays offline) if I should ever lose my primary. You can actually just enter the same text code/Barcode into your secondary phone and it would still work just like normal. It can scale to unlimited number of phones. Just make sure you keep secondary/tertiary phones physically secure.Google AuthenticatorAuthy

Just imagine this very possible scenario. You've invested in a coin, and it's went up 1,000%, you're all excited.
