Twitter resets users' passwords by mistake

Twitter has mistakenly reset the passwords of "a large number" of its more than 140 million active users while conducting routine security screening to identify accounts that may have been compromised.
"In instances when we believe an account may have been compromised, we reset the password and send an email letting the account owner know this has happened," Twitter said in its blog.
"In this case, we unintentionally reset passwords of a larger number of accounts, beyond those that we believed to have been compromised."
The mix-up triggered warnings on technology blogs and in tweets that the online messaging service had been attacked by computer hackers.
Carolyn Penner, a spokeswoman for the social networking site, said there had not been a security breach.
She declined to say how many Twitter accounts were affected by the error.
"We apologise for any inconvenience or confusion this may have caused," Twitter said in its blog.
