Error enabling Syncing Platform Authenticator in Settings

Hi,

When trying to enable this through Settings -> Developer, the Switch constantly turns back Off once leaving and returning to the page.

Attempting to use the Platform authenticator according to the steps here

Leads to the error:

The operation couldn't be completed. Syncing platform authenticator must be enabled to register a platform public key credential; this can be enabled in Settings > Developer.

Erasing the entire device worked for me. Assuming it was because iCloud Keychain was not enabled prior to that.

  • This is correct. iCloud Keychain must be on to use passkeys.
