ID Lock
If you or someone else enters your password incorrectly several times, your ID automatically locks to protect your security and you can't log in to any Campus-wide IT authentication platform service.

 ■ Your locked ID is automatically unlocked after for a given length of time.
 ■ When you log in to Campus-wide IT authentication platform service before your ID is locked
  by a malicious cyberattack, you can use the services.


Proper Password Management
If your password is compromised by a third party, they will be able to steal your identity and have access to, delete or modify: your email, research data, and your personal information. Most likely, you will not be the only victim, as they can use your password to gain access to other systems and steal data, or hack other institutions or corporations.
As having a password compromised is extremely dangerous for an individual and the university, we would like you to pay extra attention to the following points for proper daily password management:

 ■ Do not use the same or similar password for SNS, networking, or other systems/services;
 ■ do not give out your password to anyone; this includes the system administrator, parents,
   and friends;
 ■ never write your password down, as other people may see it;
 ■ do not input your password into systems/services where security is not ensured; and
 ■ change your password as soon as you think your password may have been leaked or compromised.

Best Practices For Developing Secure Passwords
Password hacking tools are getting more sophisticated each day, making it imperative to set secure passwords, otherwise your account can be easily compromised. There are password databases of common passwords available to third parties that make it easy for your account to be hacked within even a few seconds, even if you have created an exceptionally long password.
Please follow the guidelines below to develop a password that is unique to you and easy to remember.

A secure password is made up of:

 ■ Made-up words that only you know;
 ■ a string of characters that others can not make sense of;
 ■ something not found in a dictionary;
 ■ a string of characters including symbols; and
 ■ a string of characters that follows a certain pattern or rule that only you are familiar with.

A bad password is:

 ■ Birthdates, telephone numbers, license plate numbers, etc. Numbers that can be easily traced
   to you;
 ■ your address or pet’s name, nickname, etc. Information that can be easily obtained by a third
   party;
 ■ place names or people’s names;
 ■ celebrity names or character/mascot names;
 ■ words that appear in a dictionary (especially English words);
 ■ common words or popular phrases;
 ■ a password that is the same as your user ID, a repeated version of your ID or a password slightly
   changed from your user ID;
 ■ letters that are replaced with similar looking numbers (o=0, i=1 or ! etc.); or
 ■ passwords that repeat or follow a keyboard pattern (123456, 222222, abcdef, qwerty, etc.)
