Describe your problem

After doing some research, I have found that the only example available for implementing WebAuthn with Flutter is for Flutter web, which is not suitable for our native app. Since there is no API way for the WebAuthn flow, one must use a browser, but there is no flutter SDK to accomplish this. Also, the Android WebView does not support the WebAuthn standard, so what's the proper way to accomplish biometric authentication in a native flutter app?

We would like to migrate completely from Keycloak to the $690 ORY plan, but this is a blocker which we can't seem to solve ourselves. Any help would be appreciated! Thanks! 👍

Describe your ideal solution

The ideal solution would be an API way to accomplish this, without having to use a browser.

Thanks for reaching out!
@jonas-jonas do you have any guidance on what the best approach is here?

I am not too familiar with WebAuthN on native applications, and was under the impression that the only way of getting it to work was with Passkeys on iOS. Great to hear, that Android supports it, too. And even the full standard, not just a subset, as it seems.

As for the Ory Network - I believe that we do not support WebAuthN on native devices for now. The current implementation of it is pretty browser focused and requires JS and browser APIs (as you mentioned).

We do however have it on the roadmap and would love to support WebAuthN in its full capacaty on all supported devices in the (near) future.

Hello contributors!

I am marking this issue as stale as it has not received any engagement from the community or maintainers for a year. That does not imply that the issue has no merit! If you feel strongly about this issue

• open a PR referencing and resolving the issue;
• leave a comment on it and discuss ideas on how you could contribute towards resolving it;
• leave a comment and describe in detail why this issue is critical for your use case;
• open a new issue with updated details and a plan for resolving the issue.

Throughout its lifetime, Ory has received over 10.000 issues and PRs. To sustain that growth, we need to prioritize and focus on issues that are important to the community. A good indication of importance, and thus priority, is activity on a topic.

Unfortunately, burnout has become a topic of concern amongst open-source projects.

It can lead to severe personal and health issues as well as opening catastrophic attack vectors.

The motivation for this automation is to help prioritize issues in the backlog and not ignore, reject, or belittle anyone.

If this issue was marked as stale erroneously you can exempt it by adding the backlog label, assigning someone, or setting a milestone for it.

Thank you for your understanding and to anyone who participated in the conversation! And as written above, please do participate in the conversation if this topic is important to you!

Thank you 🙏✌️
