@ErikJonker @dukeboitans @pojntfx Indeed. The trade-off would be to either have lower security (impersonation risk) or worse usability (e.g. 2-factor authentication). Since age verification is going to be a gate-keeper that will lock out everyone who does not have access to a verification tool from large parts of the internet, I think it is at least worth considering the "worse usability" option as an alternative for users who do not have access to an Android/iOS phone with Device Attestation.
