How It Works
This tool runs entirely in your browser or device memory. None of the generated passwords or passphrases are stored, tracked, or transmitted over the internet.Available Modes
- Random Password: Combines uppercase letters, lowercase letters, numbers, and symbols in any length from 4 to 128 characters. You can also exclude lookalike characters (
0,O,l,1,I) to prevent transcription mistakes.
- Memorable Passphrase: Combines clean words separated by hyphens, dots, or spaces. Easy to type on keyboards, yet hard for computers to crack.
- Numeric PIN: Generates 4 to 12-digit PINs with an option to filter out predictable repetitive patterns like
1234or9999.Understanding Entropy & Crack Time
Information entropy measures how many guesses an attacker needs to find your password.
- Under 45 bits: Weak. Fast offline attacks can crack it in minutes.
- 60–84 bits: Strong. Resists brute-force attempts for years.
- 85+ bits: Very strong. Mathematically infeasible to guess even against distributed GPU clusters.
