Useful secrets, without a vault.
This tool generates new values only. It does not ask for, test, or store your existing credentials.
Cryptographic randomness
Generation uses crypto.getRandomValues, not
predictable Math.random output.
Zero retention
No account, server log, history list, or recovery feature exists for generated values.
Generate a new secret, then manage it safely.
A generator solves only one part of account security: creating an unpredictable value. Every important account should receive a unique secret so that a breach at one service cannot unlock another.
Password or passphrase?
A random character password is compact and well suited to a password manager. A randomly selected multi-word passphrase can be easier to type. Do not turn a favorite quotation, name or predictable sentence into a “passphrase”; human choices are much less random than generated words.
Practical defaultFor an ordinary account that accepts it, generate at least 16 characters with upper- and lowercase letters, numbers and symbols, then save it directly in a reputable password manager. Use the service’s exact length and character rules when they differ.
Entropy is an estimate
The displayed bit value describes the generator’s theoretical choice space under its assumptions. It does not measure device security, clipboard exposure, phishing resistance, website storage practices or whether the same password is reused elsewhere.

Common questions
Password generator FAQ
Does the generator save my result?
No. It does not create an account, history or recovery copy. Save the new value in your chosen password manager before leaving the page.
What randomness does it use?
The generator uses the browser Web Crypto API rather than Math.random. The security of the full workflow still depends on your browser, operating system and device.
Should I paste an existing password here?
No. The tool creates new values and does not need an existing password. Avoid entering current credentials into password-testing pages.
Are UUIDs passwords?
Not automatically. UUIDs are primarily identifiers. Use the dedicated password or API-key mode when a secret is required and follow the receiving system’s format rules.
What should I do after generating a password?
Store it in a reputable password manager, enable multi-factor authentication when available and never reuse it on another account.
