Phase 8 · Authentication Across the Stack
TopicsPassword Hashing
Part of the Full Stack Developer Roadmap.
Summary
Never store passwords in plain text — bcrypt is a slow, salted hashing algorithm your backend uses to store and verify passwords securely.
How to Learn This
- 1Hash a password with bcrypt on signup and verify it on login.
- 2Learn why bcrypt is deliberately slow, unlike a fast hash like SHA-256.
- 3Understand this happens entirely on the backend — the frontend never sees or stores a hash.
