# Register passkeys in Authenticator on Android or iOS devices
This article shows how to register a passkey by using Authenticator on your iOS or Android device by directly signing in to the Authenticator app or by using [Security info](https://aka.ms/mysecurityinfo). For more information about the availability of Microsoft Entra ID passkey (FIDO2) authentication across native apps, web browsers, and operating systems, see [Support for FIDO2 authentication with Microsoft Entra ID](concept-fido2-compatibility.md).
*The easiest and fastest way to add a passkey is to add it directly in the Authenticator app.*
Alternatively, you can add a passkey from your mobile device browser or through cross-device registration by using another device, such as a laptop. Your mobile device needs to run iOS version 17 or Android version 14, or later.
