## About

[Passage by 1Password](https://1password.com/product/passage) unlocks the passwordless future with a simpler, more secure passkey authentication experience. Passage handles the complexities of the [WebAuthn API](https://blog.1password.com/what-is-webauthn/), and allows you to implement passkeys with ease. 

Use [Passkey Flex](https://docs.passage.id/flex) to add passkeys to an existing authentication experience.

Use [Passkey Complete](https://docs.passage.id/complete) as a standalone passwordless auth solution.

Use [Passkey Ready](https://docs.passage.id/passkey-ready) to determine if your users are ready for passkeys.



### In authentikit

Authentikit evaluates the passkey readiness of a user's browser. Results gathered by this tool can be viewed at the [Passkey Ready page](https://console.passage.id/passkey-ready) in Passage Console. This function will use a combination of browser-defined WebAuthn utility functions and the user-agent to determine what passkey features are supported by the browser and post the results to Passage. This function will only post results to Passage once every 24 hours.
