Manage Personal Vault and Computer Login Independently

OneDrive Personal Vault MFA and your computer login are completely separate systems. You can configure them independently to suit your security preferences.

Multifactor authentication for OneDrive Personal Vault is tied strictly to your Microsoft Account security settings. Enabling it protects the sensitive files inside the Vault but does not change the sign-in method used to access your Windows or Mac operating system.

Configure OneDrive Personal Vault

Open your OneDrive folder, double-click 'Personal Vault', and follow the on-screen prompts to set up MFA (such as SMS, email, or an authenticator app) specifically for this folder.

Configure Windows Sign-in Security

To adjust your computer's login security, open the Start menu, go to Settings > Accounts > Sign-in options, and configure Windows Hello, a PIN, or a password.

Configure Mac Sign-in Security

If you are on a Mac, click the Apple menu, go to System Settings > Touch ID & Password (or Users & Groups), and manage your device login requirements there.

Manage Personal Vault and Computer Login Independently

Layered Security: Because these systems are separate, you maintain a layered security approach. Even if someone accesses your unlocked computer, they will still need to pass the MFA challenge to open your Personal Vault.

Frequently Asked Questions

Can I use Windows Hello to unlock my OneDrive Personal Vault?

Yes. While Personal Vault and computer login are separate, if you have Windows Hello (PIN, fingerprint, or facial recognition) set up on a compatible Windows PC, you can authorize it as an authentication method to unlock your Personal Vault for convenience.

Why does Personal Vault keep locking automatically?

OneDrive Personal Vault is designed to lock automatically after a period of inactivity (typically 20 minutes on desktops and 3 minutes on mobile devices) to ensure your files remain secure if you step away from your device.

Do I need a Microsoft 365 subscription to use Personal Vault MFA?

No. The MFA feature for Personal Vault is available to all OneDrive users. However, users without a Microsoft 365 subscription are limited to storing a maximum of three files in their Personal Vault.
