  "ideal_answer": "No. Passwords must be hashed using a slow, salted algorithm designed for passwords—such as Argon2id, bcrypt, or scrypt—before storage. Database encryption is valuable defense-in-depth but does not protect passwords if the database is accessed by insiders, stolen with encryption keys, or breached via the application layer. Hashing ensures that even if data is exposed, passwords cannot be trivially recovered. Never store or return plain-text passwords; implement a secure password-reset flow instead. Optionally, add a server-side pepper for additional protection."
