# Built-in Derby users

Derby provides a simple, built-in repository of user names and passwords.

To use the built-in repository, set derby.authentication.provider to BUILTIN. Using built-in users is an alternative to using an external directory service such as LDAP.

    derby.authentication.provider=BUILTIN

You can create user names and passwords for Derby users by specifying them with the derby.user.UserName property.

Note: These user names are case-sensitive for user authentication. User names are SQL92Identifiers. Delimited identifiers are allowed:

    derby.user."FRed"=java

Note: For passwords, it is a good idea not to use words that would be easily guessed, such as a login name or simple words or numbers. A password should be a mix of numbers and upper- and lowercase letters.

- Database-level properties
  When you create users with database-level properties, those users are available to the specified database only.
- System-level properties
  When you create users with system-level properties, those users are available to all databases in the system.
