Password Requirements

For the 2025 academic year, passwords must meet requirements for length, character types, and all listed conditions.

Required password conditions

Set your password to 10–20 characters long. It must include at least one character from each of these four types: uppercase English letters (A–Z), lowercase English letters (a–z), numerals (0–9), and symbols that can be used in the information system. All listed conditions must be satisfied. The guideline also restricts password strings that can be easily guessed by others or identified through analysis, but the specific strings and the complete restriction are not shown in the supplied information.
