    Password security beyond the meter

    Length, unpredictability and uniqueness are central to password strength. Predictable patterns and reused credentials are risky even if they contain symbols and capital letters.

    Worked example

    A password manager can generate a unique random password for each account. A long passphrase made from independently chosen random words may also be easier to remember than a short complicated password.

    Accuracy and best practices

    Enable multifactor authentication and be alert to phishing. Do not enter your real account password into a service unless you trust how it handles and stores input.

    Important notes

    Password entropy estimates depend on assumptions about how a password was generated. A displayed score is guidance, not a guarantee that a password cannot be guessed or stolen.

    Password Strength Checker: How to Use It

    Check the estimated strength of a password by entering a candidate in the tool. Prefer long, unique, randomly generated passwords, and do not reuse passwords across accounts.

    Tips for Strong Passwords

    Use a trusted password manager to create and store unique credentials. Enable multifactor authentication where available. A high score does not protect against phishing or leaked passwords.

    Frequently Asked Questions

    Does a strong score guarantee security?

    No. Password reuse, phishing and account recovery weaknesses can still compromise an account.

    Should I share my password to test it?

    Do not share passwords with other people or untrusted services. Check the tool privacy model before using real credentials.
