Example say my code is 123456 for gmail, 234567 for coinbase and 345678 for blockchain.
It shows
123456
123456
234567
234567
345678
345678
Is there a way to delete the copy of it? Thus why does it repeat? I was going to delete the 2nd line such as 123456 but it said if u remove it, then i can't use google authenticator? Really confused with this isse on my iphone.
There is an identifier right under the big number, mostly your login name or email address. That's all what's needed, you can delete the duplicate rows. Always print out the qr code and scan it from the print, then put the page in a folder in case you need to backup. If you do an iPhone backup with iTunes, you must encrypt the backup with a password, else your authenticator settings will not be stored.
