What Makes a Password Secure?
Password security is primarily determined by entropy, which is a measure of how unpredictable a password is. A high-entropy password is long, uses a mix of different character types, and avoids common patterns or dictionary words.
Our Password Generator is designed to create high-entropy strings that are resistant to brute-force and dictionary attacks.
Understanding Character Complexity
By including multiple character sets, you exponentially increase the number of possible combinations:
- Lowercase & Uppercase: Adds 52 possible characters per slot.
- Numbers: Adds 10 more possibilities.
- Symbols: Adds special characters, making the search space even larger.
We also provide options to exclude similar characters (like 'i', 'l', '1') and ambiguous symbols to ensure your passwords are easy to read and type when needed.
Why Local Generation Matters
Online password generators that send your password over the network are a security risk. This tool uses the crypto.getRandomValues() API, a cryptographically secure random number generator (CSPRNG) built into your browser. Your passwords are generated locally and never leave your device.
🔒 Privacy Commitment
Like all tools in the Dev Tool Kit, this Password Generator operates 100% client-side. Your data is processed locally in your browser and is never sent to our servers. Privacy is not just a feature; it's our core architecture.
