MFA Passkeys
1. What is a Passkey?
A passkey is a modern, phishing-resistant way to sign in without using a password!
- Instead of something you know (like a password), a passkey uses something you have (your phone or device) and something you are (Face ID, Fingerprint, or device PIN)
- The credential is stored securely on your device and is never shared with the website or service that you're signing into. Because of this, passkeys can't be reused, stolen by fake websites, or guessed.
- Passkeys are based on industry security standards (FIDO2). Your device proves to Microsoft that it's really you, without ever sending a password across the internet.
- If the site is not legitimate, the passkey simply won't work, and there's nothing for the attacker to steal.
- Your device becomes your key, and your identity stays locked inside it!
- Did you know that passwords are the weakest link in modern security? They are often:
- Reused
- Phished
- Leaked in breaches
- Guessed
- Microsoft's goal with passwordless sign-in is to:
- Eliminate passwords as an attack target - No passwords means nothing to phish, reuse, or brute-force.
- Reduce account takeovers and phishing - Passkeys only work on the real Microsoft sign-in and approved services. Fake sites can't trick your device into handing over a credential.
- Make sign-ins faster and simpler - Approving with Face ID, fingerprint, or a device PIN is quicker than typing passwords and codes.
- Improve both security and user experience - Stronger security without extra steps, fewer account lockouts.
Passkeys are part of Microsoft's move to a passwordless future where accounts are protected by your device and biometrics instead of passwords that can be stolen, guessed, or phished
2. Syncable Passkeys
A passkey lets you sign in without typing your password each time. It uses your device's built-in security, such as Face ID, fingerprint, screen lock, or device PIN.
We recommend saving your passkey to:
- Apple Passwords (if you use iPhone)
- Google Password Manager (if you use Android)
