> Supposedly, using the QR code on the smartphone triggers an SMS sent from your phone to Google in order to verify your phone number.

Does anyone have a better source of information than this one forum comment from someone who thinks scanning a QR code is enough to get your phone to send a text message?

Regarding how easy simswap is in 2026, it's dangerously stupid from Google to rely on SMS

I think it's probably enough to get your phone to open your texting app with a pre populated number and message body, then all the user needs to do is hit send.

It probably opens a prefilled text message and the user still has to hit send. That's the only API I know on iOS anyway.

		Can confirm this is what scanning the QR code does. I just went through this to get my Google dev account verified.
