Are generated passwords saved on a server?

No, passwords exist solely in your device's volatile memory and are never transmitted over the internet.

What is password entropy?

Entropy measures the unpredictability of a password in bits; 60+ bits provides strong security against brute-force attacks.

Yes, multi-word passphrase mode combines random dictionary words for easy memorization.

Security

Generate cryptographically secure, random passwords and passphrases with entropy strength meter.

Cryptographic Strength:Very Weak (0 bits entropy)

Brute-force crack time: Instant

Upper: 0

Lower: 0

Numbers: 0

Symbols: 0

Uses cryptographically secure window.crypto.getRandomValues for true randomness

Custom length slider (8 to 128 characters) and bulk batch generation

Toggles for uppercase, lowercase, numbers, and ambiguous symbol filtering

Real-time password entropy (bits) and crack-time strength calculation

Drag the slider to your desired character length (e.g. 16–32 chars).

Toggle uppercase, lowercase, digits, and special symbols.
