You can change passwords for users whose accounts are in the internal database. You might perform this task if the security of the old password has been compromised.
In the Security Console, go to the Home page.
Use Quick Search to find the user.
Select the user whose password you need to change.
Under User Profile, click Edit User.
In the Password section, enter the new password in the Password field.
Enter the new password again in the Confirm Password field.
