Evaluate password characteristics without treating a strength score as a security guarantee

Password-strength checks can identify obvious weaknesses such as short length, limited character variety or common patterns.

A displayed score cannot know whether a password was reused elsewhere, leaked previously or generated predictably.

Useful password-review workflows

  • Compare candidate passwords during testing.
  • Identify very short or simple patterns.
  • Teach basic password-quality concepts.

Security reminders

  • Use unique credentials for important accounts.
  • Prefer a reputable password manager for managing long random credentials.
  • Use multi-factor authentication where available.

Before relying on the result

Keep the source until you have checked the generated output. The source and destination formats can represent structure, layout and metadata differently, so important documents should be reviewed in the application or device where the result will actually be used.
