My experience is, passwords are a 1 second affair: open website, tap credential highlighted by password manager, trigger face/touch id or whatever exists on android/windows, done.
Email experience: open website, click login, get some link, go to another app, wait for it to pull emails, look for email, open email, click link, opens in browser, maybe not the same browser where you opened the app, so go back and copy link, realize copying links from email buttons is not easy on mobile, finally login.
If this is where you guys want this to go, it sucks. How can we improve it? Maybe we need to implement some wait to do what apple does when you get a 2FA code via sms? It just shows it to you in app instead of having you open messages app?
