Personal Vault is a protected area in OneDrive where you can store your most important or sensitive files and photos without sacrificing the convenience of anywhere access. It requires strong authentication method or a second step of identity verification, such as your fingerprint, face, PIN, or a code sent to you via email or SMS. This provides an extra layer of security for your locked files, keeping them more secure in the event that someone gains access to your account or device.
Personal Vault is easily accessible from onedrive.com, your PC, or other compatible devices. So, if you need a bit more security for your files, you can set up Personal Vault to take advantage of the feature.
