Password Strength Checker – Test Your Password Strength and Get Improvement Tips
Password strength checker analyzes your password and provides strength rating plus concrete improvement suggestions. Checking happens entirely in your browser — your password never leaves your device.
The tool evaluates length, character diversity, predictability and checks against databases of known breached passwords. See estimated cracking time with modern computers.
How long does it take to crack a password?
A 6-digit numeric code gets cracked in seconds. An 8-character letters+numbers+special characters password takes about an hour to crack. A 12-character equivalent takes hundreds of years. A 16-character random password is practically unbreakable with current technology. Longer is always better — each additional character multiplies cracking time.

Enter a password and the tool evaluates its strength and shows how long it would take to crack.
- Evaluates password strength: weak, fair, strong, or very strong.
- Shows estimated cracking time with brute force attacks.
- Provides concrete tips for strengthening your password.
Strength assessment is based on length, complexity, and commonality – it doesn't know if the password has been breached before.
- A long random password is always stronger than a short complex one.
- Commonly used passwords (123456, password) are weak regardless of length.
- Password uniqueness (different for each service) is as important as strength.
Your password isn't sent anywhere – checking happens entirely in your browser.
- The tool doesn't store or send your password to any server.
- Even a strong password won't protect against phishing – be careful with links.
- Use two-factor authentication (2FA) in addition to strong passwords.
