This PR fixes two bugs with Webauthn support: * There was a longstanding bug within webauthn due to the backend using URLEncodedBase64 but the javascript using decoding using plain base64. This causes intermittent issues with users reporting decoding errors. * Following the recent upgrade to webauthn there was a change in the way the library expects RPOrigins to be configured. This leads to the Relying Party Origin not being configured and prevents registration. Fix #22507 Signed-off-by: Andrew Thornton <[email protected]> Co-authored-by: wxiaoguang <[email protected]>
