Dynamic IP consequences

Disclaimer: I'd send a private ticket, but the website form only allows ban appeals as tickets, and GMs ingame told me to use the website, so here I am.

I'm currently using mobile data to play WoW, which domes with dynamic IP and there's nothing I can do about it. As a result I have to enter an authentication code on a daily basis. What's worse, I sometimes get logged out during the IP switch which sometimes happens during fights, escort quests, dungeons and what not. Is it possible to disable the log in authentication for me?
