            Bug ID: 213895
           Summary: WebAuthn problem with uv = required for getAssertion
           Product: WebKit
           Version: Safari Technology Preview
          Hardware: iPhone / iPad
                OS: Other
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebCore Misc.
          Assignee: webkit-unassigned at lists.webkit.org

In iOS 14 developer beta
The authenticator has a pin set:

The Authenticator is attached over USB/Lightning.

If in WebAuthn uv is unset, or set to preferred authentication works as expected the user is prompted for a pin and the credential is asserted with uv=1 in authenticator data.
If in WebAuthn uv is set to discouraged authentication works as expected the user is not prompted for a pin and the credential is asserted with uv=0 in authenticator data.

If in WebAuthn uv is set to required, the user is prompted to insert and activate the security key.  After doing UP the dialogue is stuck until it times out.

NFC attachment seems to have the same issue. 

Strange preferred works but not required.
