Compatibility issue with FluentAuth passkeys

The FluentAuth plugin (https://wordpress.org/plugins/fluent-security/) recently added support for passkeys. When I have Cloudflare Turnstile enabled for WordPress Login and I’m using a passkey with FluentAuth, I noticed one particular use case where it consistently fails: when the use logs in via their email address and password and is then prompted for the passkey. Turnstile is not shown and this error messages shows to the user: “There has an error when log you in. Please try to login again.” Disabling Turnstile for WordPress Login resolves the issue.

Interestingly, if the user clicks FluentAuth’s “sign in with a passkey” button first (i.e., does not enter their email address and password), everything works as expected.

Disabling Turnstile for WordPress Login resolves the issue for now, but it would be great if this could be resolved.

Thanks for your work on this outstanding plugin!
