An email sent to some Twitter users warning them that their accounts may have been compromised was sent in error, according to Twitter.

“Twitter believes that your account may have been compromised by a website or service not associated with Twitter. We’re reset your password to prevent others from accessing your account,” said Twitter in an email to some users.

Of course, users took to Twitter to ask if this warning was legit.

Over the last day or so, you may have seen plenty of tweets that look like this if you searched the network:

Hey @twitter is this e-mail requesting to reset my password really coming from you? pic.twitter.com/06fvP8I8eS

Although the message was in fact from Twitter, it was sent in error.

“We unintentionally sent some password reset notices tonight due to a system error. We apologize to the affected users for the inconvenience,” said Twitter in a statement.

This isn’t the first time that this has happened. A little over a year ago, Twitter sent the same email to many users–but that time the company had a reason. In November of 2012, Twitter believed that a small subset of user account had been compromised, but they accidentally reset too many user passwords–way more than they felt had possibly been compromised.
