How to Use the Strong Password Generator
-
1
Choose mode: "Random Password" or "Memorable Passphrase".
-
2
Adjust length slider (8 to 64 characters) or word count (3 to 8 words).
-
3
Toggle uppercase, lowercase, numbers, symbols, and avoid ambiguous characters (0, O, l, 1, I).
-
4
View password entropy score and estimated crack time, then click "Copy to Clipboard".
Practical Example & Use Case
Common Real-World Scenario
Generating high-entropy 20-character passwords with symbols for database credentials or personal password managers.
Technical Notes & Limitations
Browser Engine Architecture
Uses the browser's window.crypto.getRandomValues() CSPRNG engine. Generated passwords exist only in active client RAM.
Frequently Asked Questions
Are generated passwords ever sent to any server?
Never! Passwords are created entirely in your browser using cryptographic random number generators.
What is entropy in passwords?
Entropy measures randomness in bits. Over 80 bits is considered crack-proof against modern supercomputers.
