What Is a Passkey?
A passkey is a new, safer way to sign in to your accounts, like your Microsoft account, without needing a password. It uses your fingerprint, face, or a security key to prove it’s really you, making it much harder for hackers to get in.
You can use a passkey to sign in to Microsoft apps and websites. This includes Microsoft 365 and Copilot. You can use them on desktop and mobile browsers. On your Microsoft account sign-in screen, choose Sign-in options. Then select face, fingerprint, PIN, or security key.
Why Use a FIDO Security Key?
A FIDO security key is a small physical device, like a USB stick, that adds a strong layer of protection to your Microsoft account. You plug it in and use your fingerprint or a PIN to sign in, which is much safer than just a password.
A FIDO security device is a small physical key. You hold it in your hand. It adds extra security to your online accounts. You plug the device into your computer or phone. Then you verify who you are. You do this with your fingerprint or a PIN code. Only then can you access your account.
