3.1 What is an account?

The right to use an information system or an information service is called an account. There are various methods to certify if a person has an access right. The ECCS uses the following information:

• Username
  Unique name assigned to each user that a computer can recognize. It may also be called an account, account name, or login name.
• Password
  A password is like a PIN code of a cash card of a bank that works as a key of the account. It is known only to the user and the computer system. Even the system administrator cannot access a password of the user.

By pairing these two sets of information, an identity of a user is verified. Operation or system to verify the access right is called “authentication.” In a narrow sense, the pair consisting of the username and password is called an “account.”

Username and password are issued as a proof of the access right, and lending or transferring them to some other person is a violation of the usage rules. Using an account of someone else who has the right to access the system without acknowledgement is a violation of law.

An account of the ECCS is linked to UTokyo Account (see “3.2 UTokyo Account”) where the ECCS access right is granted to a UTokyo Account to enable each service of the ECCS.
