I know that we can choose to prompt the user to change the password at first use when we are creating the account, but I wonder if there is a way to any user by itself to change the password any time when is using the data base ? 

EDIT:

 

Create a field for NewPass, and a script step:

 

Reset Account Password[Account Name: Get(AccountName); New Password: NewPass]

 

 

Reason for edit:  See following posts

It is not safe to store the password in a field - ever.

 

How about the scrip-step made for the purpose?  Change Password[]?

Of course! My brain cramp!

 

If your users have custom privilege sets, in order for this to work, the privilege set(s) must have the  Allow User to Modify their Own Password privilege set, or the script that contains this script step must be set to Run Script with Full Access Privileges.

Understood ... happens to me all the time!

 

Thank you for adding more information about the privilege set; I dropped the ball a bit on explaining it.
