Password generator — strong random passwords, locally
Make a fresh random password for an account, then save it in your password manager. Generation uses your browser’s cryptographic random source.

Use a different password for each account and save it in a password manager. The strength figure is an estimate, not a guarantee. Copying also places the password on your device’s clipboard; reloading this page does not clear that copy.
How to use
- Choose Length. Start with the 20-character default if the destination accepts it. Use a different password for each account.
- Match the site’s rules. Choose letters, digits and symbols that the site allows. Check the finished password against any required character types.
- Copy password. Save it in your password manager before changing settings or choosing Generate another, which replaces the displayed password.
Questions
What does the strength readout tell me?
It is a rough comparison based on length and available characters, not a measured cracking time. The entropy calculation assumes uniform choices and does not fully model the generator’s character-set adjustments. Real attacks also depend on rate limits and how the destination hashes and stores passwords; the label is not a security guarantee.
Should I turn on Skip look-alikes?
It helps when someone must type the password from a screen or printed note: 0/O and 1/l/I are easy to confuse. For a password manager that fills it automatically, leaving all characters available is fine.
Is the password sent to a server?
The generator uses crypto.getRandomValues in this browser and has no password-upload or password-history feature. The page can still make network requests to load site resources. Copying puts the password on your device’s clipboard, where clipboard history or sync may keep it.
Does a long password protect against everything?
No. A unique random password helps against guessing and reuse attacks, but not a convincing phishing page or an infected device. Enable multi-factor authentication where available and keep the saved password somewhere you control.
