Unlike a typical app you download and install, the HMD DeviceKit is tied to a cloud-based authentication system. You cannot simply install it and start using it. You must first have a registered account that has been explicitly granted permission to access the tool.
HMD Device Kit is a proprietary service tool developed by HMD Global
Wait, the user might be mixing terms from different contexts. For example, a device kit (like a Dev Kit) for an HMD might require authentication via username and password, possibly through a link sent to the user's email. Or perhaps they're referring to a setup process where after purchasing an HMD and device kit, you register using a username and password, and access some resources via a link. Maybe there's security concerns around sharing such credentials.

Because individual consumers cannot easily register for official HMD developer accounts, a network of independent remote tech support channels has emerged.

Do not attempt to change the password on the compromised account first; instead, administrative teams must globally revoke the active session tokens and disable the specific user profile from the main identity directory (Azure AD, Okta, etc.). This kills any active malicious connections instantly. Step 2: Rotate API Keys and Webhooks

Update firmware and drivers
However, HMDs introduce unique risks, including physical theft (allowing brute‑force attacks on PINs) and the challenge of typing complex passwords in a head‑mounted interface. To mitigate this, developers should use password managers, enable two‑factor authentication (2FA) on the associated platform account, and avoid hardcoding credentials into any app manifest. Additionally, the device link should always be accessed over HTTPS or a local encrypted tunnel to prevent eavesdropping.
