waiting for auth...
Yes there is, you will have to contact support – go to the accounts forum and use the support link at the top of the forum.
Here is the sticky on that forum: https://forum-en.gw2archive.eu/forum/support/account/How-to-Submit-a-Ticket-Account-Issues-2
It isn’t wise to turn off email authentication, but, of course, you can.
Authentication will eventually learn the full range of dynamic IPs, and stop asking you to authenticate that address, if you save said addresses.
Might want to look into mobile Authentication as it replaces the email one. Much less annoying to type in a code from your phone than wait for an email. Also much more secure (email accounts can get hacked).
