What is a security key? We currently support several designs and providers of security keys using the Fast Identity Online (FIDO2) passwordless authentication protocols. These keys allow you to sign in to your work or school account to access your organization's cloud-based resources when on a supported device and web browser.

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..
