Any way to have account logged out at all locations?

It came to my attention not earlier that my account was compromised. From what I can tell, no trades were completed, but a number were attempted. I messaged all individuals and told them to not trade with this account as a precaution.

I confirmed that my computer was clean, changed my password and enabled 2FA. However, I'm not sure if this would log out whoever had control of my account out if they're logged in already. I was wondering if there was a way to log the account out at all locations to ensure there were no further issues.

Any help would be greatly appreciated.

 

Ask for a SRB (Self-Requested Ban), if I have read correctly before should force log out anyone who may be logged on. Ask for un-ban and log in with 2FA enabled.
