I move around a lot and use Cell internet as my primary connection which tends to give me a different location ID every time I log in. This being the case, every time I start the browser and enter my normal password it then asks me to enter the "one-time" passowrd that they emailed to me. Is there any way to turn this off? Or even better, not have to enter my normal password every time I open the launcher?

There's no option to disable one-time password.

The only way to disable the one-time password is to use a Security Key - either a physical keyfob one, if you have one (they stopped making them a while back, so they cannot be purchased new any more); or the smartphone app version.

 

Details on the Security Key setup are here.

Use SW:tOR key authenticator on your android or attach SW:tOR key to Microsoft authenticator if you have windows phone. Also it will grant you 100 Cartel Coins every month. Edited August 9, 2016 by jozocuric

thank you for pointing out that there is a Microsoft version for those few of us without an android device really appreciate it!

There's also an iPhone app for the security key.

winauth if you want another option for PCs & I'm sure there are Linux apps too (just to lazy too look atm) Edited August 9, 2016 by GythralSWTOR
