Master Passwords vs. PIN Gating: The Two-Tier Security Model You Need
Typing a 16-character alphanumeric master password every time you need to autofill a login is secure, but introduces significant user friction. However, leaving your vault completely unlocked in browser memory is a security vulnerability. Let's look at how PassCrypt balances security and convenience using a two-tier key gating model.
The Usability Dilemma
Security is only effective if users actually follow it. If a password manager makes unlocking your database frustratingly slow, users will inevitably bypass the controls: they will extend session timeouts to days or write their master passwords down on sticky notes.
Yet, if a session remains active while you step away from your desk, anyone with physical access to your unlocked computer can open your vault. This physical threat requires a solution that is fast but secure.
PassCrypt Two-Tier Gating Model
PassCrypt resolves the security/usability conflict by separating high-level wallet decryption from local user interaction.
Our two-tier model works as follows:
- Primary Decryption (Master Password): The master password is run through Argon2id on initial login. It decrypts the Data Encryption Key (DEK) and places it into browser RAM (SessionStorage). This requires significant computational power (~1 second execution time).
- Secondary Gating (Quick Access PIN): Instead of locking the entire database, individual vault entries are gated behind a 4-to-6 digit Quick Access PIN. When the browser is idle, or when you request a password reveal, PassCrypt prompts you for the PIN.
- Instant Revocation: The PIN gates the UI component. If a user enters the wrong PIN multiple times, the browser instantly wipes the DEK from SessionStorage, locking the vault fully and requiring the Master Password to log back in.
