With email magic link I need to enter my email (it seems to rarely auto-fill for some reason), then wait (often it takes 10s for the email to be sent for some reason), then if I was logging in on something that isn't my default browser I need to copy+paste the link (often just clicking the link authorizes the source session but not always and you don't know what this site does so you need to do it to be safe). Now you are finally logged in but probably have two tabs open. Either you need to find the first one to continue your session (if it logged that one in) or close it and lose your history for that tab (and hope that the website actually maintained your target page which more often than not it didn't).
