Tell HN: Gmail enabled 2FA with the YouTube app

Yesterday I urgently needed to print something, so I tried signing in to GMail on a library PC.

GMail requested that I verify my identity using a code sent to the YouTube app on my mum's phone.

Thankfully this time I was able to provide the information they needed, but I'm shocked that Google enabled 2FA without my consent.

There doesn't seem to be a way to disable this. Now I'm afraid of logging in to Google services on any computer or phone, in case the account decides to use those devices to verify my identity in future.
