Passlock vs iCloud Keychain: What's the Difference?

This is the most natural comparison for Passlock, because both Passlock and iCloud Keychain are built on Apple's native Keychain. They share the same secure foundation, so the differences are about sync, philosophy, and a few capabilities — not about which encryption is stronger. Here is the honest breakdown.

What they share

Both store passwords in the macOS Keychain, which means both inherit Apple's hardware-backed encryption. Neither is "more secure at rest" than the other in any meaningful sense, because the underlying vault is the same. See how the macOS Keychain works.

Sync

iCloud Keychain syncs your passwords across all your Apple devices through iCloud, end-to-end encrypted. This is its biggest convenience: set up an iPhone and your Mac passwords are already there.

Passlock is local and offline. It does not sync your vault to iCloud or anywhere else. Everything stays on the Mac. If you want passwords on multiple devices automatically, iCloud Keychain has the edge; if you want nothing leaving your machine, Passlock does.

Cost

iCloud Keychain is free and built in.

Passlock is a one-time $14 purchase for three Macs.

So why pay for something built on the same Keychain that Apple offers free? Because of what comes next.

The focus locks

This is the real reason Passlock exists. iCloud Keychain stores and fills passwords — that is its entire job. Passlock does that too, but adds the ability to deliberately lock a password so you cannot use it for a while:

• A time lock that seals an account for anywhere from minutes to weeks.
• A word challenge that makes you type many random words before unlocking.
• A partner password held by someone you trust.
• A master lock that puts your whole vault behind one of these conditions for deep-focus sprints.

iCloud Keychain has no concept of this. If your goal is purely to store passwords, you do not need Passlock. If your goal includes putting friction between yourself and distracting accounts — social media, shopping, anything you compulsively log into — that is precisely what Passlock adds.

Control and interface

iCloud Keychain is minimal and woven into the system; you manage it through the Passwords app and System Settings.

Passlock gives you a dedicated, focused interface for managing and locking passwords, separate from the system UI.

Who should choose which

• Stick with iCloud Keychain if: you want free, automatic sync across Apple devices and only need to store and fill passwords. For many people, it is genuinely enough. See is iCloud Keychain enough.
• Choose Passlock if: you want your passwords kept fully offline on one Mac, prefer a dedicated interface, and — above all — want the ability to lock yourself out of tempting accounts.

The honest bottom line

If you just need a password manager and you are all-Apple, iCloud Keychain is free, secure, and sufficient. Passlock is for the specific person who wants local-only storage and built-in friction for focus. It is not trying to out-sync Apple; it is offering something Apple's tool simply does not do.
