“Magic email” login is the most stupid method to me. Yeah, just make it impossible to log in with my password manager. The average person probably has the weakest password for their email anyway so if a hacker has access to their account you just made it 100% easier for them to log in.

It’s one of those dark patterns that prevents account sharing. So if you use a magic email login, nobody can share their account with their family & friends and everybody has to pay. Profit!
