Twitter has advised users to change their passwords after a small data leak.
Twitter Support tweeted:
Basically what happened was that Twitter was storing your password unencrypted(in plain text) in some of their internal logs. They have told users that they have fixed the leak.
According to Twitter, there is no evidence that the passwords were stolen by hackers or used by Twitter employees.
Even though that there is no breach, Twitter still recommends that you reset the password of your Twitter accounts.
