How the strength check works

As you type, the checker estimates entropy from length and the mix of character types, then penalises common patterns like dictionary words, repeats and keyboard runs. The result is a rough rating with concrete suggestions to improve it.

A password strength checker estimates how hard a password is to crack from its length, character variety and predictable patterns. Type a password and the meter updates instantly in your browser — nothing is sent, so it is safe to test real passwords.

How to make a weak password stronger

Add length first, then variety. Avoid names, dates and common substitutions (p@ssw0rd). A random string from a generator, or a long unrelated-word passphrase, scores far higher than a short "complex" one.

FAQ

How is password strength actually measured?It estimates how hard a password is to crack based on its length, the variety of character types, and predictable patterns like common words or sequences. Length and unpredictability raise the estimate; dictionary words and repeats lower it.

Why is my long password rated weak?Length helps, but a password built from a common word, name, or simple sequence is still easy to guess because attackers try those first. Mixing in unrelated words and character types raises the score more than padding with repeats.

Is it safe to type my real password into a strength checker?Here it is, because the check runs entirely in your browser and nothing is sent or stored, so you can safely test a real password. As a habit, avoid checkers that transmit what you type to a server.

Does a strong rating mean my account cannot be hacked?No. A strong password resists guessing, but it cannot protect you from phishing, reused-password breaches, or malware. Pair a strong unique password with two-factor authentication for real account security.
