# derby.connection.requireAuthentication

The derby.connection.requireAuthentication property turns on user authentication for Derby.

When user authentication is turned on, a connection request must provide a valid user name and password.

Derby uses the type of user authentication specified with the derby.authentication.provider property.

If the derby.authentication.provider property specifies NATIVE authentication, Derby behaves as if derby.connection.requireAuthentication were set to TRUE, regardless of how derby.connection.requireAuthentication has been set by other means.

For more information about user authentication, see "Configuring user authentication" in the Derby Security Guide.

## Default

False.

By default, no user authentication is required.

## Example

    -- system-wide property
    derby.connection.requireAuthentication=true
    -- database-wide property
    CALL SYSCS_UTIL.SYSCS_SET_DATABASE_PROPERTY(
        'derby.connection.requireAuthentication',
        'true')

## Dynamic or static

Static. For system-wide properties, you must reboot Derby for the change to take effect. For database-wide properties, you must reboot the database for the change to take effect.
