Genius idea: Notion app doesn't use passwords

Notion – The all-in-one workspace for your notes, tasks, wikis, and databases.

I've been trying the Notion app (notion.so) and just realized it doesn't use passwords. So they can't be hacked which is great, but I wonder what other impact this has...

• Less users churning out because they can't get logged in?
• Reduced support tickets dealing with lost or forgotten passwords?

What do you think? Would you try it with your product?
