What this tool does
This random password generator uses the browser's cryptographic random source to create one password from 8 to 64 characters. Choose lowercase letters, uppercase letters, numbers and symbols, then review an estimated entropy value. It does not create passphrases or batches, check breaches, or store passwords; the generated value stays in your browser.
How to use it
- Set a password length from 8 to 64 characters.
- Choose lowercase, uppercase, numbers and symbols.
- Generate the password, review the entropy estimate and copy it.
Privacy
This tool runs entirely in your browser. Your input is never uploaded, stored or shared — closing the tab removes it.
Frequently asked questions
- How does the random password generator work?
- It uses the browser's cryptographic random source to choose each character from the sets you enable, rather than a predictable general-purpose random function.
- How long should a generated password be?
- Longer random passwords generally provide a larger guessing space. Follow the destination site's rules and use a different password for every account.
- What if a website does not allow symbols?
- Turn off Symbols and generate again. At least one character set must remain enabled, and each website decides which characters it accepts.
- Does the entropy estimate guarantee a secure password?
- No. It estimates the search space from length and selected character sets; it cannot account for reuse, phishing, site rules or device security.
- Are generated passwords uploaded or stored?
- No. Generation and copying run in the browser, so LocalTools does not receive or store the password.
