A user cannot use a role until it is activated. You can require that a user enter a password before activating a role. This increases the level of security for the role.
Setting a password for a role
Select the role icon, then choose File | Properties.
If the role has a password, click Change Password on the General tab, in the Password group box.
If the role does not have a password assigned, select the Required box.
In either case, the Change Password for a Role dialog box opens.
Enter a password for the role in the New Role Password box.
Enter the password in the Confirm New Password box.
Click OK.
