If you think about this for a moment, you’ll realize that your password does not actually matter. The only thing that matters is that you have access to the email address that’s associated with your account.
Thanks to the password reset functionality that every website uses, every website already supports passwordless login — they just don’t call it that.
I’m not sure that password reset systems are as convenient as just entering a password, but maybe that’s the point. The widespread use of passwordless login systems would certainly reduce the problem of users who opt for lazy passwords, such as “password1”, “password2” etc. That said, if the same users were to continue using lazy passwords for their email, they’d still be screwed.
