Configure verification methods as fallbacks

You can now configure each verification method listed under the Assurance and Verification tab as Fallback only, in addition to enabled or disabled.

What's new

• Fallback only: A method with this setting is offered only after the user has attempted another verification method and that attempt didn't produce an age signal (no conclusive age determination). It won't appear in the initial list of methods.
• Why it helps: You can keep a stronger or alternative method in reserve for cases where a lighter method couldn't reach a verification outcome, without showing every option up front.
