How do you secure user passwords?

• Always hash passwords before storing (never store plaintext).
• Use strong, slow hashing algorithms like bcrypt, argon2, or scrypt.
• Add a salt to each password (bcrypt does this automatically).
• Use libraries like bcrypt:

const bcrypt = require('bcrypt');
const hash = await bcrypt.hash(password, 10);

• When verifying:

const match = await bcrypt.compare(inputPassword, storedHash);
