Changing the password can be done periodically if you have a password policy in your company (see Password Policy) or whenever needed.
To change your password, go to Settings - Change Password:
Change Password window in Astrow Web
To reset a user password from the system, go to Security - Users. Select the user(s) you want to reset the password for and click :
Resetting user password from Users tab in Astrow Web
The user will receive a new password by email.
Please note that this is the only way of receiving the new password. If the user does not have an email address, the administrator should set an email address (personal or standard hr) to receive the password and communicate it to user afterwards.
