Bulk update stored credentials for items in Portal for ArcGIS using the ArcGIS API for Python

Summary

When there are a lot of services added to ArcGIS Enterprise with stored credentials, and those credentials get updates, it could be very time-consuming to update them manually. 

Procedure

The below script automates updating the credentials by finding the items added to Portal for ArcGIS with stored credentials, and updating the credentials to the desired ones.

from arcgis.gis import GIS

gis = GIS("https://dns.esri.com/portal", "username", "password")
token = gis._con.token

content = gis.content.search(query="",max_items=10000)

def updateStoredCredentials(content):
    for item in content:
        if 'sourceUrl' in item:
            item = gis.content.get(item.id)
            properties = {"url":item['sourceUrl'],
                          "serviceUsername":"updatedusername",
                          "servicePassword":"updatedpassword",
                          "token":token,
                          }
            item.update(item_properties=properties)
            print(f"Successfully updated {item}")
            
updateStoredCredentials(content)
