Passlock vs Bitwarden: Which Should You Use?

Bitwarden and Passlock are both well-regarded, but they take very different approaches. Bitwarden is a popular open-source, cross-platform password manager with a famously generous free tier. Passlock is a Mac-only, offline app that adds deliberate locks for focus. Here is an honest comparison so you can pick the one that fits.

Platform support

Bitwarden runs everywhere: macOS, Windows, Linux, iOS, Android, and all major browsers. It is one of the most broadly compatible managers available.

Passlock is macOS only. It is built around the native macOS Keychain and is not intended for other platforms. If you need cross-platform coverage, Bitwarden is the clear choice.

Sync and data location

Bitwarden syncs your encrypted vault through its cloud (or a server you self-host, since it is open source). It uses zero-knowledge encryption, so your data is protected even from Bitwarden.

Passlock stores passwords locally and works entirely offline — nothing is ever uploaded. This eliminates the risk of a server-side breach and keeps your data strictly on your Mac, at the cost of handling sync yourself. See offline vs cloud password managers.

Open source vs proprietary

Bitwarden is open source, which many security-conscious users value because the code can be audited publicly and even self-hosted.

Passlock is a proprietary Mac app. It relies on Apple's audited Keychain for storage rather than its own server infrastructure.

Pricing

Bitwarden has a genuinely useful free tier and an inexpensive premium subscription.

Passlock is a one-time $14 purchase for three Macs with lifetime updates — no subscription, but also no free tier.

Features

Bitwarden covers the full password-manager feature set: cross-device sync, sharing, secure notes, two-factor code storage, and more.

Passlock focuses on local password management plus a unique capability: locking individual passwords or your whole vault behind a time delay, a word challenge, or a partner's password, to help you resist compulsive logins.

Who should choose which

• Choose Bitwarden if: you want cross-platform support, value open source, like a strong free tier, or want the option to self-host.
• Choose Passlock if: you are on a Mac, want fully offline storage, prefer a one-time purchase, and want built-in friction to curb distracting accounts.

The honest bottom line

Bitwarden is an outstanding, affordable, cross-platform password manager and a great default for most people. Passlock is a specialized Mac tool for those who prioritize offline storage and want to lock themselves out of temptation. If cross-platform sync and open source matter most, pick Bitwarden. If "offline on my Mac, with focus locks" describes you, Passlock is purpose-built for it.
