The operating model

A key, a context, and a version.

01
Derive the private key
PBKDF2 strengthens your master key using the account context.
02
Generate deterministic bytes
HMAC-SHA-256 combines the key, context, policy, and version.
03
Encode the policy
The result is shuffled into a compliant password with no storage.
