If you need to change your SOLIDWORKS Workgroup PDM user password, this can be done directly within the SOLIDWORKS add in for Workgroup PDM.
Right click within the Workgroup PDM tab in the Task Pane and select “SOLIDWORKS Workgroup PDM Options…”
Go to the “Vault” tab, under the “Password” section click “Change” to modify the existing serial number.
You will need to know your current password in order to change it to a new one. If you do not know your current password, your Workgroup PDM Administrator can modify the password also through the Workgroup PDM VaultAdmin tool.
