When a Yubikey or other fido2 device has FIPS mode enabled, UV will always be required and cannot be disabled. Unhelpfully, when it is not sent down, the hardware token (not the library) returns a generic FIDO_ERR_MISSING_PARAMETER: $ systemd-cryptenroll --fido2-device=auto --fido2-with-client-pin=no foo <...> libfido2: rx: payload_len=1 libfido2: fido_rx: buf=0x55c9ce170940, len=1 libfido2: 0000: 14 libfido2: cbor_parse_reply: blob[0]=0x14 libfido2: fido_dev_get_assert_rx: adjust_assert_count Failed to ask token for assertion: FIDO_ERR_MISSING_PARAMETER This can be set even when the token doesn't support UV (as in, fingerprint reader), in which case using the PIN is required. Check if 'alwaysUv' is set, and if not already configured, force either UV (if available) or PIN when enrolling.
