How to use the Strong Password Generator
Drag the length slider or click a quick-length button to set the number of characters in your password
Toggle uppercase letters, numbers, and symbols on or off to match the character rules of the site or app you are creating the password for
Enable Exclude Ambiguous to remove characters like 0, O, l, 1, and I that are easy to confuse when reading or typing a password manually
Use Quick Presets to apply recommended settings for common use cases like strong account passwords, numeric PINs, Wi-Fi keys, and maximum security passwords
The strength meter, entropy value, and estimated crack time update in real time as you change your rules before generating
Click Generate to create a new password using the Web Crypto API for true cryptographic randomness rather than Math.random
Use the Batch tab to generate 5, 10, or 20 passwords at once with the same rules, useful for provisioning multiple accounts
The Analysis tab shows an entropy comparison table across different lengths using your current character set to help you choose the right length
The History tab tracks every password generated in the current session so you can copy one you generated earlier without needing to store it elsewhere
Enable the Mask toggle to hide all passwords on screen for privacy when generating passwords in a shared or public environment
