Score password entropy and estimated crack time, with practical improvement tips.
SecurityType or paste the password you want to evaluate into the input field.
The strength meter updates in real time showing entropy in bits and estimated crack time.
Read the feedback to see which patterns are making the password weak.
Adjust your password until the crack time reaches at least 'centuries'.
Quickly audit your current passwords to find which ones need replacing.
Demonstrate to colleagues or students why 'P@ssw0rd' is dangerously weak.
Confirm that a memorable passphrase like 'correct-horse-battery-staple' is genuinely strong.
Run sample passwords through the scorer as part of an internal security review.
Score password strength by entropy and estimate how long a modern attacker would need to crack it. Useful for picking memorable yet safe passwords and spotting patterns that look strong but aren't.
Generate MD5, SHA-1, and SHA-256 hashes for any text input.
Encrypt or decrypt text with AES-256-GCM using a passphrase. Runs entirely in your browser.
Generate time-based one-time codes (TOTP) and the QR code to add the secret to any authenticator app.
Compare two hashes, or hash text or a file to verify integrity ā MD5, SHA-1, SHA-256, SHA-512.
Detect and mask emails, phone numbers, credit cards, and Thai national IDs in any text.
Generate passwords with custom patterns, character sets, and rules for maximum control.
