Login confirmation.
I'm in Russia, where all messaging apps are blocked, and I can't receive push notifications from abroad. However, your website regularly requires this method of identity verification. To avoid login issues, I disabled two-factor authentication. However, every time I log in, I have to go to a different email address to confirm my login!!! Why do I need a Yahoo email address if I'm forced to have another one anyway? I'm not particularly concerned about privacy; I'm sure accessing my correspondence won't be a problem, no matter how secure I am. So why bother with this?
