How generation stays trustworthy
The same ideas we use for Key Features—plain language, real cryptography.
Web Crypto API
Uses the Web Crypto API for cryptographically secure randomness. All password generation happens entirely in your browser—your password never leaves your device.
Unbiased Randomness
Uses rejection sampling so every character has an equal chance of being selected, eliminating bias and making passwords harder to predict or crack.
Smart Strength Analysis
Advanced strength estimation analyzes patterns, common words, and realistic crack times for an accurate security assessment.

Share passwords without leaving them in chat
PrivateNote's password generator runs entirely in your browser with cryptographic randomness. Generate a strong password locally, copy it, or share it through a browser-encrypted one-time note link.
It is built for handing off a newly created password—not for storing every login long-term. Use a password manager to keep accounts and PrivateNote when you need to deliver a secret once. For passphrases or numeric PINs, passwords.lu offers dedicated generators with the same browser-local model.
