We've been using Magic Links for a few years (and yes, one reason was to avoid the security issue of storing user passwords when we were just at MVP stage) and found the top problems with it are:
1. Some users (0.1%) just don't ever get the email. We tried sending from our IP, sending from MailGun, sending from PostMark, having a multi-tier retry from different transactional tools. Still, some people just will not ever be able to log in.
2. People click old Magic Links and get frustrated when a 6-month old link "doesn't work". We've decided to remedy that by showing them a page that re-sends the link and explains the situation (like Docusign does) instead of an error message.
3. People will routinely mis-spell their email and then blame the system when they don't get the code.
All of this still results, I feel, in way fewer support tickets than the email+password paradigm, so I'm still in favor of Magic links.
