Secure OneDrive Personal Vault with Face Recognition in Windows 11

What you need before you start

Check these four things first. Most failures trace back to one of them.

• A compatible camera. Windows Hello facial recognition needs a camera that supports it, usually an infrared (IR) camera. A standard webcam often does not qualify. If your PC has no compatible camera, the face option stays unavailable, and Personal Vault falls back to a PIN, fingerprint or a code.
• A personal Microsoft account. Personal Vault is a feature of OneDrive for personal accounts. It is not available for a work or school account.
• A Windows Hello PIN. Windows requires a PIN before it lets you add face recognition. You create it during the setup steps below if you don’t have one.
• A drive formatted as NTFS (the standard Windows drive format). OneDrive’s local folder must sit on an NTFS drive for Personal Vault to work on a PC. The system drive on Windows 11 is NTFS already, so this only matters if you moved your OneDrive folder to another drive.

How face recognition and Personal Vault work together

Face recognition does not encrypt your files. It is one of several ways to prove you are the account owner when the vault is locked. Personal Vault accepts other proofs too, such as a fingerprint, a PIN, a code sent by email or text, or the Microsoft Authenticator app (a Microsoft app that approves sign-ins and creates codes). On a PC with Windows Hello set up, Windows shows its own verification window, and your face is the quickest option.

The vault keeps its contents in a separate area on your drive. BitLocker (Windows drive encryption) protects that area. The vault locks again after a period of inactivity.

While the vault is unlocked, anyone sitting at your PC can open the files. Lock your screen with Win+L when you walk away, and lock the vault yourself when you finish.

Turn on facial recognition in 🪟 Windows 11

This section sets up the Windows Hello face sign-in that Personal Vault will use. If you already sign in to Windows with your face, skip to the next section.

Check that your PC supports Windows Hello face

Look at the sign-in options before you try to set anything up. This tells you right away whether your hardware qualifies, and it changes nothing on your PC.

1. Press Win+I to open Settings. The Settings⚙️ window opens.
2. Go to Settings › Accounts › Sign-in options. A list of sign-in methods appears.
3. Find Facial recognition (Windows Hello) in the list. Select it to expand the section.

You should see a Set up button. On some builds the button is labelled Get started. If the option is greyed out or shows a message that it is unavailable, the likely causes are:

• The camera is not compatible with Windows Hello face recognition.
• The camera driver (the software that lets Windows use the camera) is missing or out of date. Run Windows Update and check for a driver from your PC maker.
• Camera access is blocked. Check Settings › Privacy & security › Camera and make sure camera access is on.
• Your organisation manages the PC and has turned Windows Hello off. Only your IT team can change that.

If the option is unavailable and you cannot fix it, use a fingerprint reader or PIN for Personal Vault instead. Face recognition is not possible on that hardware.

Set up face recognition

1. Open Settings › Accounts › Sign-in options. The sign-in methods are listed.
2. Select Facial recognition (Windows Hello). The section expands.
3. Select Set up (or Get started). Windows asks you to confirm it is you.
4. Enter your PIN when prompted. If you don’t have a PIN, Windows asks you to create one first. Follow the prompts, then return to this step.
5. Look straight at the camera. Keep your face centred and well lit. A progress indicator shows while Windows scans your face.
6. Select Close once the confirmation screen appears.

Back in Sign-in options, the face section now shows buttons such as Improve recognition and Remove. If you wear glasses, select Improve recognition and run a second scan while wearing them. This helps Windows recognise you with and without them.

To confirm it works, press Win+L to lock the PC, then wake the screen. Windows should recognise you without a PIN.

Set up Personal Vault in OneDrive

This section creates the vault if you have not used it yet. You need the OneDrive app signed in with your personal Microsoft account. It is built into Windows 11 and runs from the notification area.

1. Open File Explorer📁. A File Explorer📁 window opens.
2. Select your OneDrive folder in the left pane. A personal account shows as OneDrive – Personal.
3. Double-click the Personal Vault folder in the list. A setup window opens the first time you do this.
4. Select Next and follow the prompts. OneDrive asks you to verify your identity before it creates the vault.
5. Complete the verification. This can be a code sent to your email, a code sent by text or the Microsoft Authenticator app. If Windows Hello is available, it can appear as an option.
6. Wait for OneDrive to finish setting up. The Personal Vault folder then opens, and it is empty.

The exact wording of the setup screens changes between OneDrive versions. The sequence stays the same: start the setup, verify your identity, then the empty vault opens.

If you cannot find the Personal Vault folder, the usual causes are:

• OneDrive is signed in to a work or school account only. Sign in with a personal Microsoft account.
• OneDrive is not running. Open the Start menu, search for OneDrive, and start it.
• Your OneDrive folder is on a drive that is not NTFS. Move it to an NTFS drive, or unlink and re-link OneDrive so it uses the system drive.

Unlock Personal Vault with your face

This is the daily use. When the vault is locked, opening it triggers the verification prompt.

Open the vault

1. Open File Explorer📁 and go to OneDrive – Personal.
2. Double-click the Personal Vault folder.
3. Select Unlock Personal Vault if OneDrive shows that button. The verification prompt follows.
4. Look at the camera when a Windows Security window asks you to verify your identity.

Windows scans your face. When it recognises you, the window closes and the vault opens with your files visible.

If the prompt asks for a code instead of showing the face scan, Windows Hello is not being offered for this verification. Look for a link such as Use a different verification method or More options in the window and check whether Windows Hello is listed. If it is not, see the troubleshooting section below.

Add files to the vault

1. Open the unlocked Personal Vault folder in File Explorer📁.
2. Drag files or folders into the vault window, or cut and paste them from another location. Moving a file takes it out of its original place, so it is no longer in the less-protected folder.
3. Wait for OneDrive to finish syncing the files (copying them to the cloud). Check the cloud icon in the notification area🔔. A completed sync shows a white or blue cloud with no arrows, and a green check mark appears on the files in File Explorer📁.

The vault blocks file sharing. If a file was shared before, moving it into the vault ends that sharing.

Lock the vault when you finish

Personal Vault locks itself after a period of inactivity, but you can lock it right away and shorten the exposure.

1. Right-click the Personal Vault folder in File Explorer📁. A context menu🖱️ opens.
2. Select Lock Personal Vault. The folder closes.

The next time you open the folder, the face scan prompt returns. Close any app that has a vault file open before you lock it, or that app may keep the file in use.

Change how long the vault stays unlocked

The vault locks itself after a set time, 20 minutes by default on a PC. A shorter time reduces the risk if you forget to lock it. To check the Personal Vault options:

1. Select the OneDrive cloud icon in the notification area🔔. The OneDrive panel opens.
2. Select the gear icon, then Settings.
3. Open the Account tab and look for a Personal Vault timer option.

If you do not see a timer option there, open OneDrive on the web, unlock the vault, and check its settings. The timer may sit in either place, depending on your OneDrive version. Use whichever one shows a Personal Vault lock option for your account.

Fix problems with face unlock in Personal Vault

These are the failures people hit most often, with the fix for each.

The prompt asks for a code instead of your face

Windows Hello must be set up for the account OneDrive is using. Check these points in order:

1. Check Settings › Accounts › Your info. Confirm you signed in to Windows with a Microsoft account, not a local account.
2. Select the OneDrive cloud icon. Confirm the email address shown is the same account.
3. Go back to Settings › Accounts › Sign-in options. Confirm Facial recognition (Windows Hello) shows Remove, which means it is set up.
4. Restart OneDrive. Select the cloud icon, select the gear icon, select Pause syncing or Quit OneDrive, then reopen OneDrive from the Start menu⊞.

If the OneDrive account differs from the Windows account, OneDrive may use its own verification codes. In that case, use the code method, or sign in to Windows with the same account.

The face scan fails or takes several tries

Poor lighting, a dirty lens or a blocked camera are the usual causes. Try these in order:

1. Improve the lighting, remove anything covering the camera, and clean the lens.
2. Open Settings › Accounts › Sign-in options › Facial recognition (Windows Hello).
3. Select Improve recognition and add another scan.
4. If it still fails, select Remove, then set up face recognition again from the start.

Face recognition stops working after an update

A Windows feature update or a camera driver change can disable Windows Hello face. Open Sign-in options. If the face section shows Set up again, run the setup once more. If the option is greyed out, update or reinstall the camera driver.

OneDrive says the vault is full

A free account holds only 3 files in the vault. Move some files out, or upgrade to Microsoft 365. Moving files out needs the vault to be unlocked.

Know what Personal Vault does not protect

Personal Vault adds a second layer. It does not make everything on your PC private. Keep these limits in mind:

• When the vault is unlocked, any person or program running under your Windows account can read its files.
• Someone who has your device unlocked can see that the Personal Vault folder exists. The folder shows even when it is locked. Only the contents are protected.
• Copies of a file elsewhere are not protected. If you copied a file to another OneDrive folder, a USB drive or an email, those copies stay as they are.
• Other devices use their own verification. Your face works only on PCs where you set up Windows Hello. On your phone or another PC, you verify another way.

Undo or turn off face unlock

You can remove face recognition without losing the vault. To do it:

1. Open Settings › Accounts › Sign-in options.
2. Expand Facial recognition (Windows Hello).
3. Select Remove. Windows deletes the stored face data from the PC.

Personal Vault then asks for another verification method, such as a PIN or a code, when you unlock it. To bring face sign-in back, run the Set up steps again.

Turning off Personal Vault is hard to reverse. Move every file out of the vault first, because anything left inside can be lost when you disable it. OneDrive on the web has a setting to disable Personal Vault. The web menu changes often, so this guide does not list its exact path. Look in the OneDrive web settings for a Personal Vault option.

What to do next

Lock your PC with Win+L, wake it, and confirm Windows signs you in with your face. Then open Personal Vault once to confirm it asks for the same verification.

If a Windows update later breaks face sign-in, repeat the Set up step in Sign-in options. If you want a backup way in, add a fingerprint or keep your PIN set so you are never locked out of the vault.
