Unable to retrieve 1Password credentials

Hello Devolutions Support Team,

I would like to report a bug in Remote Desktop Manager macOS version 2026.1.12.4 affecting the 1Password integration when DUO MFA is enabled.

**Environment:**
- RDM macOS: 2026.1.12.4
- 1Password for Mac: 8.10.21
- 1Password CLI: installed and up to date
- 1Password account type: Business (baselnetgroup.1password.com)
- MFA method: DUO
- RDM 1Password config: My Account Settings, Host: Default, Region: Global, Login method: Default

**Issue:**
When attempting to retrieve credentials from 1Password via RDM, the following error is displayed:

"Unable to retrieve 1Password credentials"

The Application Log reveals the underlying cause:

"PasswordManagerAccess.Common.InternalErrorException: Duo: Duo HTML: the main form is not found"

RDM appears to be attempting to handle the DUO MFA flow through its own embedded WebView rather than delegating authentication to the 1Password CLI / 1Password App integration. The "Connect with 1Password CLI" option is enabled in the 1Password App under Settings → Developer, but RDM does not appear to honour this and still tries to process DUO authentication internally — which fails because the current DUO HTML no longer contains the form element RDM expects.

**Steps to reproduce:**
1. Configure 1Password in RDM via My Account Settings (Region: Global, Login method: Default)
2. Enable "Connect with 1Password CLI" in 1Password App → Settings → Developer
3. Attempt to use a credential entry linked to 1Password in RDM
4. Observe the error

**Workaround:**
Using a 1Password Service Account token instead of username/password/MFA resolves the issue, but this is not acceptable as a permanent solution for our organisation due to the reduced security level (no MFA on the service account token).

**Expected behaviour:**
RDM should delegate authentication to the 1Password CLI / App integration and not attempt to handle DUO MFA via an internal WebView.

Please advise on a fix or patch timeline.

Best regards,
Lukas Schweizer
