cannot use Yubikey Security Key for MFA when Yubikey is set to require a pin (toggle-always-uv)

[dtirer]

Steps To Reproduce

1. On a Yubikey Security Key, set a pin using the Yubikey Manager and configure the key to always prompt for the pin. You can do so by running this command in the terminal: ykman fido config toggle-always-uv
2. Add the Yubikey Security Key as a Passkey / WebAuthn option in your Bitwarden account
3. Set your Bitwarden account to require MFA on Login
4. Install the Bitwarden iOS app
5. Sign-in to it using your master password
6. When prompted for MFA, select 'Launch WebAuthn' and select 'Security Key'
7. Bring the Yubikey Security close to the iPhone
8. When recognized, enter the pin for your Yubikey

Expected Result

It should have proceeded to login into and unlock my vault

Actual Result

I get stuck in a loop where it just continues to ask for my Security Key

Issue Tracking Info

• 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.
