Tried this recently on a small SaaS app; users complained nonstop about the inconvenience of having to switch to their email client. One key thing I overlooked is that the service is often used in academic presentation situations, where you're trying to log into the service on a 10-year-old lectern computer where you aren't logged into your email account. I reverted to the generic UN/PW approach and the complaints disappeared; passwords aren't perfect, but at least they're compatible with sticky notes. Plus, users prefer the familiar. I won't try the one-time-link approach again unless the app's specific use case makes passwords extra painful.
