Check how strong and secure your password is — all checking done locally in your browser.
A password strength checker is a free security tool that analyses your password and gives it an instant security rating. It estimates how long it would take to crack, identifies specific weaknesses and suggests improvements — helping you create passwords that are genuinely hard to break.
Check the strength of your current passwords to identify any weak ones that should be changed immediately.
Use as an educational tool to understand what makes passwords strong and teach good password habits.
Check new passwords before setting them to ensure they meet your security requirements.
Understand how password cracking works by seeing crack time estimates for different password types.
Common methods: dictionary attacks (trying common words), brute force (trying all combinations), credential stuffing (using leaked password lists) and hybrid attacks (words with number substitutions).
A dictionary attack tries common words, phrases and their variations (p@ssw0rd, password123) against your account. Passwords based on real words are vulnerable even with substitutions.
Crack time is an estimate of how long it would take automated software to guess your password by trying all possibilities. A strong password should take centuries to crack on modern hardware.
If one website is breached, attackers use your leaked password to try logging into your other accounts (credential stuffing). Unique passwords for every account contain breaches to a single site.
