47. Authentication and Password Handling Basics

Secure authentication requires strong password policies and safe verification.

Example

import bcrypt

password = b"secret123"
hashed = bcrypt.hashpw(password, bcrypt.gensalt())
print("Stored hash:", hashed)

# 47. Verification
if bcrypt.checkpw(password, hashed):
    print("Access granted")
else:
    print("Access denied")

✅ Lesson: Always store password hashes, not plaintext. Use bcrypt or similar secure libraries.
