What is Password Strength Checker?
This password strength checker scores passwords from 0 to 100 based on multiple criteria: length tiers, uppercase and lowercase letters, numbers, special characters, and absence of repeated characters.
The strength bar updates in real-time as you type, with color-coded feedback from red (weak) to green (very strong). All analysis happens locally — passwords never leave your browser.
FAQ
- What makes a strong password?

- Is my password stored anywhere?
- No — all analysis happens entirely in your browser. The password is never sent to any server or stored anywhere.
