The sign-in method you’re trying to use isn’t allowed

Problem

When trying to open an application in Parallels DaaS User Portal a user sees the following error:

The sign-in method you’re trying to use isn’t allowed. Try a different sign-up method or contact your system administrator.

Solution

If you’re using multi-factor authentication to prevent unauthorized access to your systems, make sure its setup using conditional access as documented in this section. Per industry standards, Parallels strongly recommends using multi-factor authentication and fully supports this in Parallels DaaS.

In some cases, if a pre-existing per-user MFA setting is configured in Entra ID, per-user MFA does not support the required exclusions for Parallels DaaS. Therefore. it is necessary to disable the legacy per-user MFA setting for the affected users and configure MFA via conditional access if required.

To disable per-user MFA:

1. Sign in to portal.azure.com.
2. In the Microsoft Entra ID admin center, under Manage, select Users

3. Select Per-User MFA from the header menu.

4. In the overview, select the affected user accounts and choose Disable.

Try to sign-in again with the affected account(s), if the problem persists, please reach out to our support department.
