This question already has an answer here:

I'm using same the login to access Stack Overflow from 3 different computers. Once I forgot my password, and had to recover/change it. When I try to access the Stack Overflow page on some computer, where I'm already logged in, it should log me out, or ask me to retype the password, but it doesn't.

  • Something to do with cookies I think. – hjpotter92 Apr 24 '13 at 8:05
  • Once you're authenticated, that authentication token is stored in a cookie, I'd imagine. Changing your password does not invalidate that token (even though perhaps it should). – J. Steen Apr 24 '13 at 8:10
  • hmm, I search for any other question, but I missed this one :( – sasjaq Apr 24 '13 at 9:03
