Question

How do I set up passkeys in ms Authenticator on my iPhone

Answer 1

To set up passkeys in Microsoft Authenticator on an iPhone for a work or school account, use the preferred flow directly in the Authenticator app.

1. Install Microsoft Authenticator from the App Store and open it.
2. If Authenticator is newly installed:
   • On the Secure Your Digital Life screen, tap Add work or school account.
   • Otherwise, tap Add account or the + button and choose Work or school account, then Sign in.
3. If the account is already added, tap the account and then tap Create a passkey.
4. Complete multifactor authentication (MFA) when prompted.
5. If prompted, tap Settings to set up a screen lock (Face ID/Touch ID or device PIN) and configure it.
6. Tap Settings again to enable Authenticator as a passkey provider:
   • On iOS 18: go to Settings > General > Autofill & Passwords.
   • On iOS 17: go to Settings > Passwords > Password Options.
   • Turn on AutoFill Passwords and Passkeys and under Autofill From, select Authenticator.
7. Return to Authenticator and tap Done to confirm Authenticator is set as a passkey provider.
8. The account now shows Passkey as a sign-in method; tap Done again to finish.

After this, Authenticator configures passkey, passwordless, and MFA sign-in according to the organization’s policies, and the passkey can be used for sign-in to supported Microsoft resources on iOS.
