Tool guide

Generate passwords and estimate strength

Generate passwords from a length and character set, or inspect character-set-based strength and brute-force time estimates.

How to use

Choose a length and at least one character type.
Check the generated value against the target service’s rules.
Copy and store it appropriately; use mock samples for analysis.

Example and expected result

Example settings: 16 characters with uppercase, lowercase, digits and symbols.
Results vary each time; a service may reject some characters.

Capabilities and limits

Scores do not detect breaches, reuse or phishing risk.
Cracking time assumes the displayed guessing speed and is not a security guarantee.

Troubleshooting

If output is empty, check the selected character sets. A high score does not prove that a password has never leaked.

Data processing and storage

Generation and analysis happen in page state without automatic saving. Device sync or other applications may access clipboard contents.
