i joined a corporation. To be able to do that I had to register my account/character on a third party site. I thought this was very sketchy. The site I authet with was https://auth.ao-eve.online/.
Should I be concerned by this action? was it stupid of me? do they have my login information with e-mail and password now? do I have to change my login information?
If I want to leave this corporation can I withdraw my account/character from their auth system, so the account/character is like new again? so that I can join another corporation?
Well I hope I didnt mess things up and destroyed my Eve Online account forever =(
Feel free to make new accounts with new passwords for groups you join, but…
Never enter your EVE password or account details anywhere other than at the official EVE website.
Groups may let you authenticate via EVE to access their internal pages and services, which is common practice, but to do that you need to get redirected to the eveonline.com domain to fill in your account details.
The link you showed looks suspiciously alike but is different, which seems sketchy indeed. Unless they redirected you to log in on the official EVE website I suggest you change your password.
