Passwords

A user must have a password to be able to connect to the database.

When passwords are created or changed, they are converted to UTF-8 before being hashed and stored in the database. If the database is unloaded and reloaded into a database with a different character set, existing passwords continue to work. If the server cannot convert from the client's character set to UTF-8, then it is recommended that the password be composed of 7-bit ASCII characters as other characters may not work correctly.

Caution

The default password for the DBA user for all databases is sql. You should change this password to prevent unauthorized access to your database. See Password security.
