Twitter alerts users to password security breach

Twitter sent out e-mails to some of its users Thursday prompting them to reset their passwords because of possible security issues with third-party applications.

"Twitter believes that your account may have been compromised by a website or service not associated with Twitter," the e-mail says. "We've reset your password to prevent others from accessing your account."

The e-mail includes a link that brings users to a password reset page, then prompts users to review their Applications and revoke access to any application that they don't recognize.

TechCrunch reports that Twitter usually sends out these types of e-mails when a significant number of accounts are hacked. Many users have Tweeted about receiving the e-mail or about having issues logging in to their accounts.

Twitter has not confirmed the size of the hack, but it told TechCrunch that users who have received the e-mails should reset their passwords from the link provided in the email or directly on Twitter.com.
