That's a tricky one. Got me a while to find out.
You have to click on your name on the top right corner and go to Dashboard. Then click on the character section and press the button Add character.
Once you provide your character's name and server it will ask you to change your character comment in ffxiv lodestone with a specific text in order to confirm it is you the owner.
And that's it, basically.
