Twitter mistakenly resets passwords of some users

SAN FRANCISCO (AP) — Twitter says it mistakenly reset the passwords of some users as part of a routine security check-up.

Thursday's mix-up triggered warnings on technology blogs and in tweets that the online messaging service had been attacked by computer hackers.

Twitter sought to clear up the confusion with a post on its website a few hours after it sent out emails alerting some users that their accounts had been compromised. Twitter says its security specialists had reset a larger number of passwords than they intended.
