V‑dash contractor unable to add trusted device (INVALIDCREDENTIALS CANCEL) – remote, no sponsor, Entra assistance needed

I am a Microsoft vendor with a v‑dash account

I am fully remote, not campus‑based, and will never be on campus. I have completed initial authentication setup (password + MFA), but I am blocked when attempting to sign in because I cannot register any device as trusted.

After authentication, the sign‑in fails with the following error:

{

  "SessionId": "1d7a7bdc-3145-0748-bf6b-425c7c781ab3",

  "Timestamp": 1775249860361,

  "Error": "INVALIDCREDENTIALS CANCEL"

}

This appears to be a Conditional Access / device trust issue rather than incorrect credentials. I understand v‑dash users cannot self‑approve trusted devices and that this typically requires Entra Identity assistance (e.g., Temporary Access Pass, MFA rebind, or trusted device reset).

Complicating factors:

  • I am fully remote (never on Microsoft campus)
  • My original Microsoft sponsor/contact has moved roles
  • I do not have access to an internal admin or help desk
  • I am effectively locked out despite valid credentials

I am requesting guidance or routing to the appropriate Entra Identity team to reset device trust or issue a Temporary Access Pass so I can complete sign‑in.

Happy to provide additional details privately if needed.

    The issue is a sign-in and device/MFA problem that cannot be fixed by the v‑dash contractor directly and requires action by a tenant administrator or Microsoft’s Data Protection/support team.

    From the provided context, similar lockout scenarios (lost/changed phone, no access to Authenticator, no alternative method, or only one/global admin) are resolved only by:

    1. Having a tenant admin reset MFA / require re-registration
      • An admin in Microsoft Entra ID must:
        • Go to Microsoft Entra admin center (https://entra.microsoft.com).
        • Navigate to Users → All users → [select the user] → Authentication methods.
        • Select Require re-register multifactor authentication so that MFA methods and device bindings can be set up again at next sign-in.
      • This pattern is described in the moderator guidance for resetting MFA methods and re-registering authentication options.
    2. If no accessible admin/helpdesk exists, engaging Microsoft support / Data Protection team
      • For business/organization accounts where the user is locked out and there is no other admin who can reset MFA or device trust, the documented path is to open a support ticket and have the Microsoft Data Protection team intervene.
      • In similar cases (for example, a single global admin locked out, or a phone number blocked for MFA), moderators indicate that Microsoft support/Data Protection can:
        • Reset MFA.
        • Clear problematic flags.
        • Restore access so that sign-in and MFA/device registration can be completed again.
      • The escalation is initiated via the regional customer service phone numbers listed in the documentation. Frontline support then raises a ticket to the Data Protection team.
    3. Use sign-in logs and Entra sign-in diagnostics (for admins investigating)
      • An Entra admin can review Microsoft Entra sign-in events to see why Conditional Access or device trust is blocking the sign-in, including device details and policy evaluation.
      • If policies are misconfigured (for example, requiring a compliant or domain-joined device that the contractor cannot provide), the admin must adjust Conditional Access or device requirements accordingly.

    Given the constraints in the question (no campus access, no sponsor, no internal admin/help desk), the only supported resolution path in the context is:

    • Identify or reach the organization’s Microsoft 365/Entra administrator (for example, via the company’s internal process or the “find my admin” guidance referenced in similar cases) and have them reset MFA and device bindings as above; or
    • If that is not possible, open a support case with Microsoft using the published customer service phone numbers so that the Data Protection team can verify identity and reset access (MFA/device trust) on the tenant side.

    The context does not provide a self-service method for a v‑dash contractor to bypass Conditional Access or register a trusted device without admin or Microsoft support involvement.
