jerry0 has a unique ability to make even the simplest things in to unsurpassable mountains of complexity.

I have answered pretty much all his questions in this thread already. Most succinctly here: https://bitcointalk.org/index.php?topic=5379158.msg58861546#msg58861546
I have also told him how awful a choice Authy is here: https://bitcointalk.org/index.php?topic=5379158.msg58858827#msg58858827

Here's what jerry needs to do:

• Ignore all this old accounts and 2FA
• Download Tofu
• Set it up with his new accounts
• Write down the 16 character codes for each account as back ups
• Use iOS Finder to make a back up of his 2FA database

Here's what jerry will do instead:
Ignore all this, continue to try and use Authy incorrectly, and make 20 more posts about it.
