React · Supabase Auth · 2026
Passwordless Login
Sign in with a six-digit code sent by email — no passwords. It is also the account page where people can delete their account and all their data themselves.
Open the login ↗What it does
- Sends a one-time code by email through my own mail setup.
- After signing in, people can delete their account: the server empties their files, messages and profile in one step.
What I learned
How authentication works behind the scenes, how to send email from my own domain, and how to design a destructive action so that nobody triggers it by accident.
