Micro-blogging site Twitter on Thursday warned its users of a change in their passwords after its attempt to reset account passwords which may have been hacked.
Many users received an email saying that the company ended up in resetting many user passwords in an attempt to fix the problems of those accounts which have been affected by a possible security breach.
"We're committed to keeping Twitter a safe and open community. As part of that commitment, 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 along with information about creating a new password. This is a routine part of our processes to protect our users," Reuters quoted Twitter as saying on Thursday.
"In this case, we unintentionally reset passwords of a larger number of accounts, beyond those that we believed to have been compromised," it said.
Meanwhile, Twitter denied the possibility of any security breach, saying that the latest password resetting was part of a routine process. The company also said that it had mistakenly reset many more passwords than required.
Twitter sent an email communication to its users asking them to reset their passwords to prevent any account breach. The email also listed steps to help users through the process.
"Twitter believes that your account may have been compromised by a website or service not associated with Twitter. We've reset your password to prevent others from accessing your account," the email read.
According to BBC, some users noticed that a few of their tweets were deleted and claimed to have found spam links on their accounts. Many users ignored the mail from Twitter, saying that the mail looked like a piece of phishing information.
Twitter has not revealed the exact number of accounts which were reportedly attacked.
