Every user of a database has a password. The password must be supplied for the user to be allowed to connect to the database.
The Password (PWD) connection parameter is not encrypted. An application can include the password in the connection string.
If both the Password (PWD) connection parameter and the EncryptedPassword (ENP) connection parameter are specified, the Password
(PWD) connection parameter takes precedence.
When creating a data source, it is recommended that you do not include the password as part of the definition. Although both
the ODBC Configuration For SQL Anywhere window in the Windows ODBC Data Source Administrator and the SQL Anywhere Data Source utility (dbdsn) have this capability, including this information poses a security risk.
On Unix, data source information is stored in a system information file (named .odbc.ini by default).
