SAN FRANCISCO, CALIFORNIA, UNITED STATES (REUTERS) – Twitter Inc urged its more than 330 million users to change their passwords on Thursday (May 3) after a glitch caused some to be stored in readable text on its internal computer system rather than disguised by a process known as “hashing”.
The social network disclosed the issue in a blog post and series of Tweets, saying it had resolved the problem and an internal investigation had found no indication passwords were stolen or misused by insiders. Still, it urged all users to consider changing their passwords.
The blog did not say how many passwords were affected. A person familiar with the company’s response said the number was “substantial” and that they were exposed for “several months.”
