How the Personal Vault works in Onedrive
From within the Windows 10 operating system, with Onedrive active, open File Explorer and then open the Onedrive folder (or search for OneDrive from the start menu to open the folder that synchronizes files on the cloud). Among the folders inside Onedrive, you will find a link called Personal Vault that if clicked allows you to configure the protection function. Going forward with the wizard, you will have to confirm your identity using verification options via email or by phone number.
When the verification is complete, the Onedrive personal vault folder will open automatically and can be added to it. files to keep protected and safe with encryption. Even on a shared PC where the same Microsoft account is used, to access the personal vault files it will always be necessary to confirm the identity by phone or email address, so there will be no risk (unless you share the email specified in two-factor verification).
If you want to configure two-factor authentication for your Microsoft and Onedrive account, you can open the account management page at this address https://account.microsoft.com/security/ and then press, at the top, up Verify in two steps.
To lock the Vault folder you can remain inactive on it for 20 minutes (in the meantime Onedrive send notifications to warn that if not used will be closed), or press Onedrive icon on the desktop to open the control box and press the button to lock the Personal Vault .
Using the free version of OneDrive, the Personal Vault allows users to archive only up to three rows inside. To eliminate this limit you need a Microsoft 365 account, even if there is a trick to upload multiple files into the Vault without paying anything: by uploading it inside zip file. In practice, you can create a zip file with all the files you want inside and then upload it to the Vault to make it count as if it were one.
Also note that the files stored in the Personal Vault cannot be shared with anyone.
Technically, the Personal Vault stores and encrypts files through Microsoft's Bitlocker-encrypt technology and also works on all versions of Windows 10, including even Home, which does not have Bitlocker support.
