Hash Passwords, Never Store Plaintext

Use Werkzeug to hash and verify passwords.

Plaintext Is a Disaster

If you store passwords as plaintext, one database leak hands attackers every account at once. The first rule of auth is simple: never save the raw password. 🔒

Hashing, Not Encrypting

You protect passwords with hashing, a one-way transform. Unlike encryption, a hash cannot be reversed back into the original password, even by you.
