The DB.UpdateDevice.Password field activity allows you to maintain your passwords in the CatTools database device password fields.
It does not run against your physical network devices as all the other Activities do but is instead used to do batch processing against multiple devices within the CatTools database Device table.
An example use of this Activity might be:
Your network devices use a RADIUS or TACACS server for remote authentication. You have just changed the password on the RADIUS/TACACS server and you now need to update all of your devices within CatTools with this new information.
Instead of editing each device individually you would create a new DB.UpdateDevice.Password field activity which will apply the new password to all of your Devices at once.
