Problem

The authfile example content in the description has redundant space and could not function normally.

See yubico pam doc, section Central Authorization Mapping, authfile should looks like:

<username1>:<KeyHandle1>,<UserKey1>,<CoseType1>,<Options1>:<KeyHandle2>,<UserKey2>,<CoseType2>,<Options2>:...
<username2>:<KeyHandle1>,<UserKey1>,<CoseType1>,<Options1>:<KeyHandle2>,<UserKey2>,<CoseType2>,<Options2>:...

Which different from here. Notice the space before second_keyHandle:
username:first_keyHandle,first_public_key: second_keyHandle,second_public_key
