OneDrive Personal Vault is the name of the new security feature launched by Microsoft in order to add additional security features to its online file storage service.
This feature will ensure that the only way to access your OneDrive files is with a strong authentication or two-step verification. This includes a fingerprint or face recognition with a Windows Hello-compatible device, PIN code or a one-time code sent by SMS or e-mail, or by using Microsoft Authenticator.
The Personal Vault will also automatically relock on a PC or device after a period of inactivity, and you’ll need to then reauthenticate to get access again.
The new feature will be available to OneDrive users on the web, on Windows 10 and through Microsoft’s mobile apps. Users in Australia, New Zealand, and Canada will soon be able to access it and it will be available to all OneDrive users by the end of the year.
Microsoft is also doubling the storage plan for its $1.99/month standalone OneDrive subscription from 50GB to 100GB. If you’re on a free plan, you’ll be able to try Personal Vault, too, but Microsoft will limit the number of files you can store in it.
All OneDrive files are already encrypted when in transit or at rest, Personal Vault just adds another layer of optional security features besides this. This was mainly designed for users who store important files like copies of passports, identification cards, or more sensitive personal financial information.
On Windows 10 PCs, Personal Vault also sets up a BitLocker-encrypted area on your local hard drive to sync your Personal Vault files.
