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.
Feature: Password Strength Meter
How strong is your password?
Keeper's password strength meter helps you understand how secure your passwords really are. Instantly test any password or passphrase.
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
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 organizational 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.
