Choosing and Managing a Secure Password
Learn how to create a secure information-system password and manage it responsibly.
Password requirements and secure management
The Tokyo Denki University Information System User Password Guidelines set rules for password length and the types of characters that may be used. To make a password harder for other people to guess or analyze with tools, use a longer character string with a variety of character types. Read the guidelines before setting your password. Manage the password responsibly so that it does not come to other people's attention.
