1Password vs Keeper — Attribute Category Vocabulary
Taxonomy of attribute categories used to classify comparison data for 1Password vs Keeper.
Which password manager is more secure: 1Password or Keeper?
Both use military-grade AES-256 encryption with zero-knowledge architecture, meaning neither can access your passwords even if breached. The key difference is Keeper's 500+ billion dark web record monitoring is more comprehensive than 1Password's Watchtower feature. For most users, both are equally secure. Keeper edges ahead for active threat monitoring, while 1Password focuses on prevention through design. Neither has ever been breached in their history.
1Password officially supports Linux through a native command-line tool and limited web access, though a full desktop client isn't available. Keeper requires using the web app on Linux or Android via phone. If Linux native app support is critical, 1Password is the better choice, but neither provides the same experience as on macOS or Windows. Users needing comprehensive Linux integration should consider alternatives like Bitwarden.
What's the best password manager for families?
1Password's Family plan ($99.99/year for 6 users) is more affordable than Keeper ($119.99/year) and offers superior usability for non-technical family members thanks to its intuitive interface. Both include emergency access features and shared vaults. 1Password's higher user satisfaction rating (4.7 vs 4.6 stars) reflects easier setup. Choose 1Password for simplicity or Keeper if your family needs dark web monitoring for peace of mind.
Does either password manager store my master password?
No. Both 1Password and Keeper use zero-knowledge encryption where your master password never leaves your device and is never stored on their servers. Even if their servers are compromised, hackers cannot access your data without your master password. This is a core security principle both follow identically, making them equally safe in this regard.
Which has better 2FA/authenticator support?
Both include built-in TOTP (time-based one-time password) generation for two-factor authentication. Keeper additionally offers a separate proprietary Keeper Authenticator app for redundancy—useful if your password vault is ever compromised. 1Password integrates TOTP seamlessly within the main app. Keeper's approach adds slight complexity but provides an extra security layer for paranoid users. For most people, both implementations are equally functional.
