Attention

For your protection we have enhanced our Portal Security Features (Updated: November 21, 2016)

  • If your current password doesn’t meet the enhanced requirements, NetClient CS will prompt you to update it the first time you log in after Thursday, November 17, 2016.
  • Your password will now expire after 90 days. In addition, your password must contain at least eight characters, including at least one uppercase character, one lowercase character, one numeric character, and one special character (such as @, #, or $). You can make your NetClient CS accounts even more secure by creating a password that’s longer than eight characters.
  • After 30 minutes of inactivity, your NetClient CS, Web Employee, and/or Employee Self-Service sessions will time out. You will need to re-enter your login credentials to continue working. Note that processes such as long print jobs will continue during the timeout.

By agreeing, you adhere to the new portal security features.
