Password strength tester

Passwords entered in this strength tester are processed only on your device and are never stored or sent to Keeper.

Keeper is built to strengthen every password

Instantly measure password strength

Keeper's strength meter instantly evaluates each password as it's created or updated. The visual indicator makes it easy to see whether your password meets strength standards before saving it in your vault.

Entropy-based strength scoring

Keeper's password strength meter uses entropy calculations to assess password complexity and predict its resistance to brute-force or credential-stuffing attacks.

Integrated with Keeper's password generator

If your password is weak, Keeper helps you strengthen it instantly. You can generate a random, complex password that meets organisational or personal policy requirements directly within the same interface.

Works across all Keeper platforms

The password strength meter is built into the Keeper Web Vault, browser extension, desktop app and mobile app. Whether you're updating a credential on your phone or laptop, you'll receive the same consistent password evaluation.

Private by design

All password evaluations are performed locally on the user's device, never on Keeper's servers. Keeper's zero-knowledge architecture ensures your passwords remain private and fully encrypted at all times.
