... or you'll need to stop using reCAPTCHA if you want to get any traffic on your Web site. I know, people will slavishly knuckle under, but let me dream for a few minutes.

99.999% of people don't give a shit and don't even know what this means. They'll follow the instructions. These are the same 99.999% of people who press win+R ctrl+V enter when the captcha prompts them to. Because do this to see the dancing bunnies.

Yeah, this is going to turn into another malware vector, isn't it?

The app that scans the code talks to the TPM in your phone to prove that your phone is running an unmodified Google OS.

Which would be meaningful if phones weren't remotely controllable. So the net effect is every AI agent will also have and connect to a physical phone.

The attestation will include a unique ID of the phone, so that if you get banned you have to keep buying new phones and keep paying money to Google. Google won't stop this because it makes them money.

And the official Google OS just won't feature remote-control software.

Discord has a feature where you can log into your account on your PC by scanning a code on your phone.

So does Binance.

... which is why you'll get locked out if you happen to visit an unusual number of sites in a day.

The requirements for the mobile devices are listed here: https://support.google.com/recaptcha/answer/16609652 So it seems that you will need a modern Android device with Google Play Services installed or a modern iPhone/iPad to be allowed to browse the web in the future. No mention of device integrity verification yet, but the writing is on the wall.

> No mention of device integrity verification yet

If Google Play services is listed as a requirement, that implies that a "certified Android" device capable of Play Integrity attestation is required, since that's the only officially supported way to obtain Google Play services. On consumer-facing support articles like this, they don't tend to get into the nitty gritty details like what APIs are being used. If MEETS_DEVICE_INTEGRITY is required, that would probably not be explicitly listed here.

E.g. the consumer documentation for Google Pay just says you need a "certified" Android device and a screen lock set up: https://support.google.com/wallet/answer/12200245

(Yes, if you go deep into the FAQ at the end it eventually states that if you rooted your phone, you can't use tap to pay, but that requirement is implied by the certification requirement [1].)

In Google's eyes, and in the eyes of the law due to trademarks filed by Google, Android == Google Android.

This feature would make little sense if it's not using device attestation because otherwise it would be easy to spoof. I expect that it will initially not use it, and they will start A/B testing device attestation in the coming years.

I believe you'll also need bluetooth enabled on both devices. At least you do for those "scan this QR code displayed on your computer to authenticate using the passkey on your phone" feature, which this seems analogous to. Bluetooth is used to ensure that the two devices are actually physically co-located.

Google building harder walls against bots while simultaneously building AI agents that need to get through them is peak 2026.

Point On! Probably done by two different teams, who don't know about each other. I hate this (re)captcha so bad. They assume everyone is bad.

Why can't an AI scan the QR code? Just fire up an emulator if necessary

Bluetooth is generally used to prove that the two devices are co-located, which makes it more complex to do your proposed kind of deployment at-scale. Bespoke solutions could perhaps work around for some smaller number of devices, this QR code layer by itself isn't intended to stop 100% of workarounds.
