I'm facing an issue with Power Automate Desktop in a proxy environment and would appreciate any insights.

Environment:

Proxy network
Office 365 license
Registry settings configured under HKLM\SOFTWARE\Microsoft\Power Automate Desktop:
- ProxyNetworkCredentialsKey
- ProxyServer

Problem: Before changing my Windows password, PAD works fine and I can create flows. However, after changing the password, PAD fails to access cloud services.

Temporary workaround: To restore access, I currently have to:

Update the Generic Credentials in Windows Credential Manager
Clear cache via Internet Options
Terminate PAD from Task Manager
Sign in to PAD again

This workaround is tedious and not ideal for regular use.
Is there a way to make PAD work seamlessly even after a password change?

Thanks in advance!

Hi,

1. Use Windows Credential Manager Automation

If you can automate the update of Generic Credentials after a password change, that saves you the manual step. You could script this:

Export current credentials before password change.
After password change, update stored credentials via script or manual input.

But this still involves some manual handling.

2. Configure PAD & Proxy for Integrated Windows Authentication (IWA) or Single Sign-On (SSO)

If your proxy supports Integrated Windows Authentication (like NTLM or Kerberos):

Ensure PAD is set to use system default proxy settings and Windows credentials for proxy authentication.
This way, when your Windows password changes, your user session tokens update, and PAD transparently uses the updated credentials without needing manual updates.

Check these:

Registry key ProxyNetworkCredentialsKey should ideally be empty or not set, so PAD uses current logged-in user credentials.
ProxyServer is set correctly.
Your proxy supports IWA (NTLM/Kerberos).
