Private, Browser-Based Password Generator
100% Client-Side Cryptographic Security
Many online password generators send the generated keys over the network, exposing them to intermediate proxies, browser extensions, or server logging. PasswordDiet computes all entropy, password generation, and time-to-crack metrics completely inside your browser using the cryptographically secure crypto.getRandomValues API. Your generated credentials never leave your screen.
How to Create the Perfect Password
- Step 1: Select your format: Alphanumeric characters, word-based Passphrase, or phonetic Pronounceable syllables.
- Step 2: Adjust the length. We recommend at least 16 characters for standard passwords, or 4 words for passphrases.
- Step 3: Refine character settings by including/excluding sets, avoiding ambiguous characters, or specifying custom exclusions.
- Step 4: Check the real-time entropy meter and crack time indicators to ensure your key stands up to GPU brute-forcing.
- Step 5: Copy the result or download a text file for bulk-generated lists.
Frequently Asked Questions
Q: Why should I avoid ambiguous characters?
A: Ambiguous characters like the letter 'l' and number '1', or letter 'O' and number '0', look very similar in many fonts. Excluding them makes it much easier to copy passwords manually (e.g., when reading from a phone screen to a laptop).
Q: What is a safe entropy score?
A: A score above 60 bits is generally considered safe from online attacks. For highly sensitive targets, aim for 80-100 bits or more, which remains secure even against offline cluster decryption attempts.
