Both IT teams and end users are afflicted by password reset tickets. IT teams will often push more urgent issues down the queue to ensure that users don't have their work put on hold while their passwords reset. Password reset tickets can be costly if they aren't addressed promptly. Nearly 30 percent of all help desk tickets were caused by forgotten passwords. It is not surprising that large companies have spent more than $1 million to resolve password-related help desk requests. It is a good habit to change passwords regularly, as it helps prevent cyberattacks caused by stolen credentials. Security experts recommend that administrators ensure that users change their passwords regularly and have password expiration policies in place.
