Microsoft has implemented the One Drive Personal Vault, a new added secure layer of your drive storage to better protect sensitive files. One Drive Personal Vault is a secure area of One Drive that contains only authenticated verification procedures or other stages of identity verification, such as your fingerprint, face, PIN, or code sent to you by email or SMS.
Personal Vault gives you an extra layer of protection for your important files, photos and videos. Personal vault has other features such as automatic locking, bit locker encryption on Windows 10. Along with Personal Vault, Microsoft also introduced the option to automatically back up your desktop, documents and picture folders to One Drive on Windows 7, 8, and 10 PCs with the One Drive Sync app. The feature was first launched in Australia, New Zealand and Canada, but Microsoft is rolling out this feature to consumers all over the world today. For those with a 100GB free or standalone OneDrive plan, you’ll only be able to store up to 3 files in your personal vault, while anyone else will be able to store as many files as possible in their Vault profile. To have unlimited personal vault capacity according to your plan, you need to be an Office 365 user, whether personal or home.
