Verify Your Identity fails with 'There are no built-in authenticators available to this browser' when opening Manage Consumer Details

Hi everyone, 

I'm experiencing an issue in a Salesforce Sandbox when trying to access: 

Setup → App Manager → View App → Manage Consumer Details 

When I click Manage Consumer Details, Salesforce opens the Verify Your Identity dialog, but the authentication immediately fails with the following error: 

There are no built-in authenticators available to this browser. 

Environment:

• Salesforce Sandbox
• Google Chrome

What I've already verified:

• Touch ID is correctly registered as my authentication method.
• Touch ID works correctly for other authentication requests.

From what I've investigated, it appears that the Verify Your Identity dialog may be rendered inside an internal iframe, and the browser is therefore unable to access the registered authenticator. 

Has anyone encountered this issue before? Is this a known Salesforce or Chrome limitation, or is there a configuration or workaround that resolves it? 

Any help or suggestions would be greatly appreciated. 

Thank you!
