About

This guide provides step-by-step instructions for setting up a Microsoft Authenticator passkey. It includes device requirements, links to prepare your iPhone or Android phone, and the steps needed to create and use your passkey for passwordless sign-in.


Does Your Phone Support Passkeys?

Before setting up a passkey, make sure your phone is running a supported operating system and Microsoft Authenticator is installed and up to date.

iPhone
iOS 17 or newer is required to support passkeys. iOS 17+ is compatible with iPhone XR, iPhone XS, and newer models. iPhone 8, iPhone 8 Plus, iPhone X, and 1st Generation SE do not support iOS 17. Before continuing with passkey setup, follow the Prepare Your iPhone for Passkey Setup instructions.

Android
Android 14 or newer is required to support passkeys. Supported devices include Samsung Galaxy S21 and newer models, as well as Google Pixel 4a (5G), Pixel 5, and newer models. Before continuing with passkey setup, follow the Prepare Your Android Phone for Passkey Setup instructions.
