Possible regression in Devolutions Password Manager 2026.3.1.9 – Autofill fails with linked credentials and password lists

Hello Devolutions Support Team,
We are experiencing an issue with the Devolutions Password Manager browser extension in Microsoft Edge.
The autofill functionality stopped working correctly recently, although the exact same configuration worked without any issues until approximately October 8, 2026.
We suspect a regression introduced by a recent update of the browser extension or Remote Desktop Manager.
Environment

• Remote Desktop Manager: 2026.3.12.0 (64-bit)
• Devolutions Password Manager extension: 2026.3.1.9
• Microsoft Edge: 155.0.4283.45 (64-bit)
• Windows: 11 26H2 (Build 26300.9457)

Problem Description
The browser extension correctly detects and displays matching entries from Remote Desktop Manager.
However, autofill fails when the corresponding RDM entry uses referenced credentials instead of directly stored credentials.
We have identified the following behavior:
Credential ConfigurationAutofill Result
Username and password stored directly in the RDM entry --> Working
Credentials – Linked (Vault) --> Not working
Credential – Find by name (User Vault) --> Not working
Credentials referenced from a Password List --> Not working

When selecting an affected entry in the browser extension, neither the username nor the password is inserted into the login fields.
Steps to Reproduce

1. Create a website entry in Remote Desktop Manager.
2. Configure the entry to use linked credentials or credentials referenced from a Password List or User Vault.
3. Open the corresponding login page in Microsoft Edge.
4. Select the matching entry in the browser extension.
5. Observe that the username and password fields remain empty.

Control test:

1. Duplicate the same RDM website entry.
2. Configure the duplicated entry with a username and password stored directly in the entry.
3. Open the same login page using the same browser and extension.
4. Autofill works correctly.

This confirms that the issue is specifically associated with referenced credentials rather than the login page itself.
Troubleshooting Performed

• Restarted Microsoft Edge and Remote Desktop Manager.
• Disabled other browser extensions to rule out conflicts.
• Verified extension permissions.
• Tested multiple websites and autofill methods.
• Inspected the browser developer console.
• Reviewed browser policies and security settings.
• Tested different HTML form configurations.

The issue persists with linked or referenced credentials.
Expected Behavior
The browser extension should automatically resolve referenced credentials from RDM and fill the username and password fields, as it did previously.
Actual Behavior
Entries are correctly detected and displayed, but autofill does not populate the login fields when credentials are referenced.
Questions

1. Is this a known regression in Devolutions Password Manager 2026.3.1.9 or RDM 2026.3.12.0?
2. Have there been recent changes to the handling of linked credentials, Password Lists or User Vault references?
3. Is there an available hotfix, newer version or recommended workaround?
4. Are there specific debug logs we can provide to help investigate this issue?

We rely on centralized credential management and would prefer to avoid storing duplicate credentials directly in individual website entries.
Thank you for your assistance.
Best regards,
Oliver
