Local generation
Passwords are generated in your browser using its built-in randomness.
Crypto randomness
Uses crypto.getRandomValues where available, with rejection sampling to reduce bias.
Copy-ready output
Generate one or many passwords, copy individually, or copy all at once.
Dynamic Password Insights
This password setup uses uppercase, lowercase, numbers, symbols.
Increasing length usually improves strength more than adding complexity alone.
Ambiguous characters are excluded for easier reading.
Each selected character set is required at least once.
Browser crypto randomness is available.

How Password Generation Works
The generator builds a character pool from selected options.
Secure random values choose characters from the pool.
Length controls how many characters are selected.
Required character sets ensure variety.
Generated passwords are shuffled after required characters are added.
Passphrases use randomly selected local words.
Character Sets, Length, and Entropy Explained
Longer passwords create more possible combinations.
Larger character pools increase variety.
Entropy estimates the password search space.
Length often matters more than complicated rules.
Excluding ambiguous characters improves readability but slightly reduces the pool.
Passphrases can be strong when words are chosen randomly.
