# Setup passkeys as MFA method for password less sign in

<p class="callout warning">To register and use passkeys your IT provider has to enable and configure the option for your environment.</p>

This guide is intended for end users and is not intended as a guide for setting up passkeys for IT administrators.

Read this guide carefully and follow the steps exactly as documented if you want to get rid of your Microsoft account password and increase security.

### What is password less &amp; phishing-resistant MFA

**Passwordless MFA** eliminates the need for traditional passwords by using methods like biometrics (e.g., fingerprints) or hardware tokens. This approach enhances security and user convenience.

**Phishing-resistant MFA** adds an extra layer of protection by ensuring that authentication methods are resistant to phishing attacks. It often involves using hardware tokens or biometric verification, making it much harder for attackers to impersonate users.

Both methods can be combined in Microsoft Account products. Your administrator can configure so called passkeys to achieve both passwordless &amp; phishing-resistant MFA with one solution.

This guide walks you through the setup process of passkeys using Android or IOS devices and your Microsoft work or school account.

### Prerequisites

- Managed Windows or MacOS device and mobile phone with Microsoft Authenticator installed.
- Requires at least Android version 14 or iOS version 17.
- Eighter your MFA method should be configured or a Temporary Access Pass (TAP) should have been sent to you by your IT provider (You can request a TAP from your IT contact person or order one for a specific time frame).

### Setup process

The setup process consists of two steps. We need a Browser where we are already signed in using our Microsoft Account and also a mobile phone. So keep the devices ready and follow the guide based on your user account state and OS preference.

<details id="bkmrk-important-note-for-b"><summary>Important note for below IOS 18</summary>

Unfortunately, iOS currently only supports one active third-party password manager. This means that if you use a password manager other than the integrated one, you must change it to Microsoft Authenticator for the passkeys to work correctly.

### Final sign in process &amp; how to use it

After you have setup the passkey to your mobile phone you are able to use this sign in method. If you are now faced with a Microsoft Login page ([https://login.microsoftonline.com](https://login.microsoftonline.com) or [https://login.microsoft.com)](https://login.microsoft.com) you will be redirected to the following dialogue (e.g. first sign in on new device).

For Android devices select the according device model or use the QR code (iPhones currently only support the second method) with the phones camera.

<table border="1" id="bkmrk--1" style="border-collapse: collapse; width: 100%;"><colgroup><col style="width: 50%;"></col><col style="width: 50%;"></col></colgroup><tbody><tr><td>[![image.png](https://docs.lucanoahcaprez.ch/uploads/images/gallery/2024-10/scaled-1680-/CWsimage.png)](https://docs.lucanoahcaprez.ch/uploads/images/gallery/2024-10/CWsimage.png)

Then you get redirected to your application or website and you have completed the sign in process.

##### Troubleshooting

If the above steps are not displayed automatically and you are prompted to enter your password, you can click on the link below the input field and you will be redirected to the experience described above.

### Conclusion

While setting up passkeys for your Microsoft Account might seem a bit more complex than traditional password + number matching, the benefits are substantial. The setup can save a lot of time and stress in the long term, particularly for Android users who can take advantage of its push capability. Please note that this method massively increases login security and phishing resistance if set up correctly.

Last but not leaste make sure that you own a valid TAP to setup correctly and check that IT has tested this accordingly (hints: Entra Conditional Access policies, Intune compliance policies, Entra Authentication Strength).
