Most of us value our security, even if we might be a bit too lazy to make every single account as safe as it can/should be, and that's the problem. It's hard to get all your accounts set up with stuff like two-factor authentication/2FA between all the different methods and the fact that you can't even set it up for all your accounts from every platform. Google just eliminated at least one barrier with a change today, though, as the company is now allowing you to enroll security keys from Android using Chrome, as well as macOS devices running Safari.
