Twitter said it has mistakenly reset a large number of passwords, over 140 million may be affected by this password reset. The reset accidentally took place when 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 on Thursday. “In this case, we unintentionally reset passwords of a larger number of accounts, beyond those that we believed to have been compromised.”
Carolyn Penner, a spokeswoman for the social-networking site said, that there had not been a security breach. Twitter has sent a large number of emails to users whose password has been reset.
