NERSC Password Policy and ProceduresA user is given a username (also known as a login name) and associated password that permits her/him to access NERSC resources. This username/password pair may be used by a single individual only: passwords must not be shared with any other person. Passwords must be changed as soon as possible after exposure or suspected compromise. Exposure of passwords and suspected compromises must immediately be reported to NERSC at security@nersc.gov or the Account Support Group, support@nersc.gov.
Password and Account Protection
NOTE: Each user is responsible for all
activities originating
from any of his or her username(s). A username/password pair must NOT be shared under any circumstances. Users who share their passwords will have their access to NERSC disabled. Users should not leave clear-text passwords in a location accessible to others or secured in a location for which protection is less than that required for protecting the information that can be accessed using the password. New UsersNERSC must have a signed user policy form on file before assigning a user a password on a NERSC system. Once this form has been signed, NERSC will contact the user by phone to assign a temporary password and to activate the username(s) on the appropriate systems. The temporary password is only good for 24 hours. The user should login to NIM with this password, and immediately choose a new password. After about 10 minutes, this new password may be used to login to any NERSC computer. Login FailuresNOTE: Your login privileges will be disabled if you have three login failures while entering your password on a NERSC machine. Call the Account Support group at 800-666-3772, menu option 2, or 510-486-8612 to have your login failures cleared. You do not need a new password in this situation. Obtaining a New Password from NERSC Account SupportIf you have forgotten your password, call the Account Support group at 800-666-3772, menu option 2, or 510-486-8612 to get a new temporary password. The temporary password is only good for 24 hours. You should login to NIM with this password, and immediately choose a new password. After about 10 minutes, this new password may be used to login to any NERSC computer. Changing Your PasswordPasswords must be changed under any one of the following circumstances:
Your new password must adhere to the Department of Energy requirements below. All of NERSC's computational systems are manged by the LDAP protocol and use the NIM password. Passwords cannot be changed directly on the computational machines, but rather the NIM password itself must be changed:
See HPSS Passwords and Authentication for instructions on how to change HPSS passwords. Department of Energy Password RequirementsAs a Department of Energy facility, NERSC is required to adhere to Department of Energy guidelines regarding passwords. The following requirements conform to the Department of Energy guidelines regarding passwords, namely DOE Order 205.3 and to Lawrence Berkeley National Laboratory's RPM §9.02 Operational Procedures for Computing and Communications. Different NERSC systems have different software environments with minor variations in software constraints on passwords. When users are selecting their own passwords for use at NERSC, the following requirements must be used. It is the responsibility of the user to select a password that adheres to the following requirements, regardless of whether or not the system is capable of enforcing them.
