    We have enhanced our eRocks password policy as part of our ongoing cybersecurity efforts. Changes include: (1) You will need to choose a new password every 180 days instead of every 365 days. (2) The minimum password length is now 8 characters instead of 6. (3) Your account will lock after 10 failed login attempts instead of 100. The next time your password expires or if you choose to change your password prior to the expiration date, you will be required to create a password that conforms to the new policy requirements. If you are locked out of your account or have any other questions, please contact Support Services at 1-800-613-8753, 919-882-2222 or at
