# ⚠️ DEPRECATED
**This repository is deprecated and no longer maintained as of January 16, 2026.**

## 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 passage-flex-rust

Use passage-flex-rust to implement Passkey Flex into your Rust backend to authenticate requests and manage users.
