# Hanko Authenticator apps

> Device compatibility for the Hanko Authenticator apps on Android and iOS.

To let your users use passwordless authentication, they need access to the Hanko Authenticator application, which handles the cryptographic authentication requests created by the Hanko service.

The Hanko Authenticator application is composed of two essential parts:

* FIDO software client
* Hanko relying party management

Whenever a user chooses passwordless authentication as a login method for your service, a (passwordless) registration request is issued. From then on, each subsequent authentication request results in a notification prompting the user to declare consent (usually by touching the fingerprint reader on their device). Afterwards, the Hanko service informs your application about the outcome of the operation, and it is up to you to decide whether the user may gain access to your application.
