Passwords must conform to the criteria listed on this page to be accepted by the CITES Password Manager.

Requirements for all passwords

Length: Eight Characters or More
All passwords must be between 8 and 12 characters in length.

Three character classes
A password must contain at least one character from each of the following three character classes:

No invalid characters
A password may only contain valid characters. Valid characters include standard printable ASCII characters (uppercase lowercase letters, numbers, and standard English punctuation). Invalid characters include white space characters (spaces and tabs), function keys, arrow keys, and accented letters.

No name or NetID fragments
A password may not contain forward or reverse fragments of three or more characters from the owner's name or NetID. For example, if John Doe has the NetID jdoe, his password cannot contain sequences such as jdo, ohn, or eod.

No large words
A password may not contain words five characters or longer in length. Smaller words are allowed. The word list used to verify passwords may include common foreign words, formal nouns (like names), and jargon not commonly found in traditional dictionaries.

No alphabetic sequences
A password may not contain forward or reverse alphabetic sequences of three or more letters. The case of the letter (uppercase or lowercase) does not matter. For example, these sequences are not allowed: abc, ZYX, mNo.

No numeric sequences
A password may not contain forward or reverse numeric sequences of three or more numbers. For example, these sequences are not allowed: 012, 876, 456.

No keyboard sequences
A password may not contain keyboard sequences of three or more characters. This includes horizontal, vertical, and diagonal rows of keys along with duplicate keys. For example, these sequences are not allowed: asd, qaz, ji9, xXx, 222.

No example passwords
A password may not match any of the example passwords ever used in CITES documentation.

Additional requirements for NetID passwords

Cannot use last password
Your new NetID password may not be the same as your current NetID password. You may reuse older previous passwords, however.

Minimum life of 24 hours
Once you change your NetID password, you cannot change it again for 24 hours.

Maximum life of one year
NetID passwords expire one year after they are set. If your NetID password expires, it cannot be used until you change it.

About these requirements

These password rules are derived from the requirements set forth by the University Technical Management Team (UTMT), which comprises the Chief Information Officers (CIOs) from the three University of Illinois campuses, University Administration, and the Hospital. The UTMT is responsible for enacting and enforcing data security policies under the University of Illinois Information Security Policy, which can be found in the Campus Administrative Manual of the University of Illinois.
