there are so many reasons why (IMHO) passwordless login is better for sites and users.
I kinda get the password manager thing but password managers users can be a small % of total users (depending on the demographic). But login is a giant frustration point for a high % of people and that’s even before you touch the functionality of the site.
Otherwise, it’s reasonable to be skeptical of the safety of your credentials. Passwordless avoids that entire category of safety.
