Password Generator
Local & private — strong random passwords, pronounceable mode, batch & presets.
Pro Advanced options
Pro Pronounceable / Passphrase
Tip: Long passphrases are easier to remember and can be very strong.
Note: For multiple results, each password is on its own line.
About this generator
This tool uses crypto.getRandomValues for secure randomness and runs entirely in your browser. Advanced options let you customize character sets, exclude confusing characters, and generate pronounceable alternatives.
How are passwords generated here?
We use the browser’s crypto.getRandomValues to generate cryptographically strong random values. All generation happens locally.
Do you store or transmit my passwords?
No. The tool runs entirely in your browser. Nothing is uploaded. Presets are stored privately using localStorage.
What is the pronounceable/passphrase mode?
It builds multi-segment strings (e.g., CVC patterns) with optional capitalization, digits between segments, and a custom separator—ideal for long, memorable passphrases.
Can I avoid confusing characters or simple patterns?
Yes—toggle “Exclude look-alikes (O0, Il1)”, “Avoid repeated characters”, and “No consecutive neighbors”. You can also require at least one from each selected set.
How do you estimate strength/entropy?
Entropy ≈ length × log2(pool size). The badge translates bits of entropy into labels like Fair, Strong, or Excellent.
Is batch generation safe?
Yes. Each password is generated independently using cryptographic randomness. You can copy results, download as .txt/.csv, or save/load presets locally.
