Re: One time account verification every time I log in.

Like many online security systems the SWTOR one time password will recognize when you're on a connection you haven't used before, if you're receiving the one time account verification extremely often then it's likely your ISP has you on a dynamic IP address in which case every time you are trying to log on your IP address is different.

This is probably an issue with how your internet connection is set up and nothing to do with the game.
