So everytime someone logs into your account from a different place you'll get coinlocked. Everytime you activate the code in your email; that account will then have access to your account, right?

So if:

1: i get hacked
2: i get coinlocked because of it
3: i fill in the code from me email ( because i want to play again obv )

Will the hacker then get access to my account without being coinlocked?

I don't get.

No.
If they were to get access they would have had to of known the code and entered at their Destination\IP.

Yea, everything is locked until you enter that code they e-mail you. Everytime it's logged in from a different location it will be locked, so hackers can't really do shit.
Pretty awesome feature.

i found that if you wanna play on a new server you get the coin lock as well, or this happened for me at least
