Ok, I think I am starting to connect the dots here. What I’m working with is not creating them within the PSU gui but allowing them to be created by the script (specifically in the authentication.ps1 file).
If I understand correctly, the rest API provided here Importing Secret Variables (with script) - #2 by adam creates the credentials as a PSU secret variable and then the Set-Secret creates the credentials in Windows Credential Manager. Is that correct? If I’m using the api call to create the credentials in PSU that way, do I still need to use Set-Secret to create them in Windows Credential manager as well?
