Password Strength Checker
Analyze your password strength in real time. No data is sent anywhere.
This tool analyzes a password in real time and estimates how strong it is - checking length, character variety, and common patterns that make passwords easier to guess. It's useful for checking whether a password you're about to use is actually strong, rather than just assuming it is.
Frequently asked questions
No - the analysis runs entirely in your browser as you type; the password isn't transmitted or stored anywhere.
Common weaknesses include short length, lack of character variety (all lowercase, no numbers/symbols), dictionary words, and predictable patterns (like "Password123") that automated cracking tools check first.
Since checking happens locally in your browser and nothing is transmitted, it's reasonably safe - but as a general habit with any tool, many people prefer testing with a similar but not identical password rather than their exact live credentials.
