Hi guys,

I have some questions to ask
1. If the USB authenticator supports both CTAP2.1 and CTAP2.0, does it also need to support CTAP2.1_PRE?

2. In the conformance tool of CTAP2.1_PRE, are there any test items that can be verified?


Thanks,
Steven

CTAP2.1 PRE is a compatibility flag that specifies that device supports experimental bioenroll and/or credmanapi

The CTAP2.1 conformant device may advertise PRE as well so long it supports bioenroll and credmanapi on the experimental HID cmds.

1. No. It does not have to, but it is adviced.

2. FIDO does not explicitly tests PRE as this is informal spec. But if you do CTAP2.1 certification then you will have bioenroll/credmanapi tested
