Attitudes like yours are why tech recruiters are notoriously inconsiderate and difficult to work with. It’s not a good look and not something to be proud of.
There’s like 2 very discrete camps in recruiting in my experience, people who optimize for short vs long game basically. I’ve maintained a fantastic relationship with the best recruiter I met, and it’s definitely not like this, there’s some great people in the long game camp.
So many different options: Shipping confirmation emails, IP addresses of connected accounts, GPS of frequent locations (i.e at nights when you're presumably sleeping), phone number for 2FA that can easily be reverse-lookup'd to PII databases, etc. etc.
