iP16, IOS18, Yubikey 5C NFC, Passkey Sign-in?

[thewho2018]

Steps To Reproduce

1. Open YubiKey Manager go to tab Interfaces verify that all boxes under NFC are checked.

2. Go to vault.bitwarden.com -> Settings on a computer and under Providers select Passkey add two YubiKey 5C NFC, make sure to save on Security Key and not fail like i did at first and save it in Windows..

3. On iPhone try to sign-in using WebAuthn. "Error has occurred".

Might just be that I'm not understanding every part of this or missing something but i have been emailing back and forth with Ethan at support and i think hes getting frustrated with me!

Expected Result

Successful sign-in.

Actual Result

Error has occurred.

• I understand that work is tracked outside of Github. A PR will be linked to this issue should one be opened to address it, but Bitwarden doesn't use fields like "assigned", "milestone", or "project" to track progress.

This issue seems to apply to a user/pass login as well (iP16 / iOS 18)
