What is database authentication?

Rating:

Database authentication is an authentication method that is used to authenticate database users. When using the database authentication method, the administration of user accounts (including password administration and user authentication) is entirely performed by Oracle. Each database authenticated user account has its own password that is stored in the database in an encrypted format. When a user enters his account name and password in order to connect to the database, Oracle compares the password with the corresponding password stored in the database. If an exact match is found, Oracle allows the user to connect to the database.

When creating or altering a user account, the IDENTIFIED BY clause can be used to specify a password for the user account. The user can change his password at any time using the ALTER USER statement.

The database authentication method is preferred when administering small user communities.
