With each Flynet Web Service application that uses Pooled Sessions support, an encrypted credentials editor is generated which has the necessary encryption codes and keys to edit the encrypted credentials.
This executable is typically named based on the project and originally copied to the c:\program files\flynet\viewer\bin folder but you can move to another folder.
Here is an example of a Logon Pools Credentials editor for a project named FVCAP--Note that your version of Flynet may have generated with an additional column to the left which enables assigning a unique userid/password combination to each session or pool ID.
When you save the credentials, the next new session created will use the new credentials
