Save your Google Auth codes when you set up 2FA, it is only a question of time before your phone breaks. If you did not do it, disable 2FA now and reenable it right after, this gives you a second chance to save the key.
Couldn't you please describe how can I do that, assuming I have full access to my account? What codes are you talking about?
The problem it that it has to be slow and tedious to work around a lost 2FA code - there would be no security in it if the hacker could just hack your gmail account and write to support. Some sites have a policy of waiting weeks before giving access if you lose 2FA!
First, I have access to my phone number, I just put my sim card into a new device, and Bitfinex has my verivied number, so they can send a text/make a call to ensure that I am not a hacker that broke someone email.
Second, it would be ok if support answered me that look, we have a protocol and you have to wait for several weeks. But I got ZERO RESPONSE from support. At all. They just ignored me. Zane Tackett and Josh Rossi on Reddit promised to take care of it and got silent since then.
And the price is going down, making me loose my money day after day.
