Is there a way to sign out from all locations on Twitter?

[Okay]

I logged into my Twitter from a friends iPhone once and now my account is on his Twitter app and he can log into my account whenever he wants & see all my notifications. He said that he can't log out of it on his phone, so I wondered if there was a way to log out from all locations from a computer?
Also, I've tried changing my password and that didnt work

Unfortunately it's not like Facebook or gmail, where u have the option to do so, but if u really need to, just deactivate ur account and wait till it's fully deactivated and then login again from ur preferred device an it should be fine and logged in only from that device.

And don't worry deactivating wont remove ur account until after 40 days, so just make sure u login again from ur preferred device and ur good to go mate.
