How do I revoke someone's access to my twitter?

[Cliff]

I used my friend's iphone to log onto my twitter one day and she never logged off. It wouldn't be a problem if she didn't unfollow people and delete tweets. I know that you can't revoke iphone access from online but she won't delete my account so I have no idea what to do.
Oh and I've tried changing my password but that didn't do anything
if you didn't read what i JUST SAID, changing your password doesn't do anything it stays logged on to every device

Try taking yur friends phone again and logout.! If tht is also nt possible then keep tweetng to yurself (@....)..yur friend will get irritated and log out.!

1. change your password, it will instantly log anyone out of anything
2. delete your account because tweet is crap
3. start using facebook
4. sue your friend for making you use tweet
5. slap your friend for making you use tweet
6. go watch some youtube
