How can i block other computer from using my origin account? [ Edited ]

[Kimmistry]

I shared my account with my friend, but i don't want no one to enter my account anymore, how can I block the IDs or, idk, block the entrance from another computer (without changing my password) 

thanks

Change your password, same links to account management or, forgot password, either will work.

Having log in verification on is also a good idea so long as you can have the verification sent someplace this "friend" does not have access to. Once it is on, you can also trust computers or mobile devices so that when you log in on those, it will not ask for a verification code but, will if you log in on a new device or, from a new IP address.

Please read Keeping your Account Secure.

Note that sharing your account with friends is a violation of the TOS (Terms Of Service) Please do not do this again.

Hmm, I see... 
Yeah, I'm not sharing anymore, on purpose...
I just want that my account wont be use by the person anymore

I know about login verification, but, there's no other way?
