Unable to Access Currently running Background process "Credential Manager UI Host" for VPN connection app.

Expected Behavior

Need to Switch to Back-ground app and click on “Allow”.

Actual Behavior

My Script is able to trigger VPN app and pass credentials then connect to VPN. But New Security key POP-UP started coming, and I am not unable to switch to that pop up to select Allow Button. Please help me if it can be possible with Pywinauto or I need to use any other library in python.

Steps to Reproduce the Problem

1. Below

Short Example of Code to Demonstrate the Problem

Below is my Script.

from pywinauto.application import Application
from subprocess import Popen,PIPE
from tkinter import ttk
import time
import tkinter as tk
 
def VPNConnect():
    app = Application().start(r'C:\windows\system32\rasphone.exe -d "<VPN_app>"')
    time.sleep(2)
    app.VPN_app1.Connect.click()
    dlg = app.top_window()
    print(dlg)
    dlg.Button.Allow.click()
    time.sleep(5)
    app.Warning.OK.click()
    time.sleep(10)
     app.VPN_app1.type_keys('user_id')
     app.VPN_app1.type_keys("{TAB}")
     app.VPN_app1.type_keys("{TAB}")
     app.VPN_app1.type_keys("{TAB}")
     app.VPN_app1.type_keys("{TAB}")
     app.VPN_app1.type_keys("password")
     time.sleep(2)
     app.VPN_app1.type_keys("{ENTER}")
     
 def VPNcheck():
     cmd = ['%comspec% /c route print 10.10.10.0'] #Command for getting VPN connection status
     result = subprocess.Popen('%comspec% /c route print 10.10.10.0', stdout=subprocess.PIPE, shell =True)
     for line in result.stdout.readlines():
         if b'<VPN_app1>' in line or b'<VPN_app2>' in line:
             return True
     return VPNcheck
 
 def popupmsg(msg):
     popup = tk.Tk()
     popup.wm_title("!")
     label = ttk.Label(popup, text=msg)
     label.pack(side="top", fill="x", pady=20)
     B1 = ttk.Button(popup, text="Okay", command = popup.destroy)
     B1.pack()
     popup.mainloop()
 
 VPNcheck()
 
 #Condition to check if the VPN is already connected and then call VPNConnect().
 if VPNcheck() == True:
     popupmsg('VPN is already connected')
 else:
     VPNConnect()
 

Below Is the error.

You have to inspect which attributes the control actually exposes. Use the print_control_identifiers() method of pywinauto. And/or for more inspection use inspect.exe or the new MS accessibility insight tool.

Did you verify procesd id of your pop up? You can do it with Inspect.exe utility, as suggested by @michel117 . As a debug step, you could hard code the pid and try to connect to it. Also, did you try to run your script as admin, to eliminate permissions problems?
