I know I was quite surprised to get a response that quick.Lucky you, I got hacked the same day no response yet.
You don't need to put random stuff, just something Not linked to GW2. for example it shouldn't be like this obviously MyGW2@whatever.comIt really is scary. I will probably go with something like 1password to help out. I should invent 1email, that I would have a main account that only I would know, and multiple random email addresses under the account, one for each website/service.
It is kind of ridiculous to have to use a new email for guild wars 2 (and possibly many other things), along with 2 step verification, and any other security features one might be able to use.
Do I really need to use 5748iio819@%*)@gmail.com as my account email, with a random string of numbers/letters/symbols as a password for guild wars 2?
It's mainly the GW2 password that needs more numbers than letters. like 444s495u32292w something like that.
