There are two real schools of password management, and most of the noise online confuses them. Let’s separate them cleanly and then talk about when each one is the right call.
Two architectures
A vaulted manager (1Password, Bitwarden, LastPass, Dashlane) stores an encrypted database of your credentials and syncs it across your devices. You unlock the vault with a master password; the provider holds the ciphertext.
A deterministic manager (MoolKey) does not store generated passwords or PINs. It recomputes each one from inputs plus a Master Key, every time, using a slow hash. Same inputs, same output, forever.
Everything else follows from that one difference.
What each one actually protects
| Question | Vaulted | Deterministic |
|---|---|---|
| Where do generated credentials live? | Encrypted, on a server | Recreated in the browser |
| What account data remains after a breach? | The encrypted vault | Non-secret account metadata and security records |
| Can it work offline? | With a cached vault | Always, byte-identical |
| Is there account recovery? | Usually yes | No, by design |
Neither row is automatically “better.” They are answers to different fears.
Where vaulted managers shine
- Autofill. A vault knows your exact stored string, so it can fill forms in one click and detect phishing domains.
- Arbitrary secrets. Notes, recovery codes, credit cards, SSH keys: anything you can paste, a vault can hold.
- Recovery. Forget your master password and most providers give you a path back in.
If those matter most to you, a well-run vaulted manager is a genuinely good choice. We mean that.
Where deterministic wins
The deterministic model avoids storing a generated credential list:
- No stored password list. A backend breach cannot expose a saved list of generated credentials, although account metadata and security records still exist.
- No generated-credential sync. Two devices compute the same answer independently. There is no credential copy to reconcile, corrupt, or fail to sync.
- No migration. Switching tools normally means exporting and importing a vault. With MoolKey there is nothing to move.
- True offline parity. The output on a plane is identical to the output online, because the network was never involved.
The honest caveats
We are not going to pretend the trade is free:
- Forget the master key and it is gone. No reset, no support ticket that helps. That is the price of nobody, including us, being able to reach your secrets.
- Rotation is per-account, not arbitrary. You bump a version integer to roll one password. You cannot pick “the exact string I want.”
- Autofill is intentionally absent. MoolKey is a least-surface launcher, not a content script crawling your pages.
How to choose
Ask yourself one question: what keeps you up at night?
If it is the friction of daily logins, optimize for autofill and pick a vault. If it is the thought of a permanent encrypted copy of your credentials sitting on someone’s server, choose a deterministic model that recreates generated credentials instead of storing them.
