I'll comment in an end user standpoint. I'm not trying to debunk your idea. I know, having an idea and acting on it is a hard thing and kudos for that. I would love easier login process on every site. I don't know your likely use case or target market. So I'm using an imaginary one based on my usage. Disclaimer: I'm not your average user. I use password managers heavily. But on the other hand every browser have some kind of integrated password manager. My imaginary scenario has these assumptions: - This website relatively simple and offers unimportant service because otherwise it's not a good practice to use this service. So my security need relatively low. - I'm using this site relatively often. Maybe a few times a week. Otherwise these points are not that important. My imaginary scenario has two cases: - I'm using my regular PC & Browser On a website using this service, I always have to open my email address and click a link to approve login. And if there is a "Remember Me" option only the first time. So my cumulative additional cost between somewhere 1 - infinity extra steps. On a regular site, I'm already in here. I'll just hit a key combination for password manager and I'm done. And if I'm using browser's password manager I'll probably just need to click login. - I'm using a new PC and/or a brand new Browser/Profile My email address has 2FA active with a really complex password. This just caused me unnecessarily 3 step instead of 1 to login.
