Password Generator
Create secure random passwords in your browser with length controls, character options, and a live strength meter. Nothing is uploaded — generation stays on your device.

How do you create a strong random password you can trust?
What this tool does
The Kitnax Password Generator creates cryptographically random passwords based on your chosen length and character sets. A live strength meter estimates entropy from length and charset variety so you can see whether a candidate meets common security baselines. Toggle uppercase, lowercase, numbers, symbols, and optional ambiguous-character exclusion to fit manual entry or password-manager workflows. Use Show to reveal the value, then Copy to paste into your manager or signup form. Generation uses the Web Crypto API entirely in your browser — passwords are never uploaded, logged, or stored by Kitnax.
Why you need it
Reused and weak passwords remain the fastest path to account compromise. Human-chosen passwords follow predictable patterns attackers exploit with dictionary and credential-stuffing attacks. A dedicated generator removes guesswork: each click produces a high-entropy string sized for modern recommendations (16+ characters). You need unique passwords per site and service, stored in a password manager rather than memorized or recycled. This tool gives you a trustworthy random starting point at the moment you create an account, rotate credentials after a breach, or provision a shared vault entry for a team.
How to use it
- Set Length with the slider — 16 characters is a strong default; increase for high-value accounts.
- Enable character sets: uppercase, lowercase, numbers, and symbols for maximum entropy.
- Turn on Exclude ambiguous when someone will type the password manually (0/O, l/I confusion).
- Click Generate Password — the strength meter updates immediately with each new value.
- Use Show, then Copy, and paste directly into your password manager before navigating away.
Practical examples
- New account signup: generate a 20-character password with all charsets, save it in your manager, and never reuse it elsewhere.
- Wi-Fi guest network: generate a 12-character password with ambiguous characters excluded for a printed card guests can type.
- Credential rotation after a breach: create fresh unique passwords for affected services instead of incrementing an old pattern.
- Developer sandbox: generate throwaway credentials for staging environments that must not match production secrets.
How it works
Entropy grows with both password length and the size of the character pool. A 16-character password drawn from 94 printable ASCII symbols carries far more combinations than an 8-character password with letters only. Kitnax samples random indices with crypto.getRandomValues — the same secure random source browsers expose to JavaScript — then maps them into your selected charset. The strength meter is an educational estimate, not a formal audit; real-world cracking cost also depends on hashing algorithms sites use on their servers (bcrypt and Argon2 are good; raw MD5 or SHA is not).
Client-side generation means your password exists only in page memory during the session. That privacy model suits password creation, but you should still clear the screen before sharing your display and rely on a password manager as the system of record. Never email generated passwords in plain text if avoidable.
Common mistakes
- Reusing one strong password across multiple sites — a breach anywhere exposes every account sharing it.
- Prioritizing complexity rules over length — a 20-character passphrase beats an 8-character symbol-heavy pattern.
- Memorizing dozens of random passwords instead of using a manager built for encrypted storage and autofill.
- Disabling symbols to simplify typing when the password will live only in a manager — you leave entropy on the table unnecessarily.
FAQ
Are generated passwords stored or sent anywhere?
No. Passwords are created locally in your browser using the Web Crypto API. Kitnax does not upload, log, or store them.
How long should a strong password be?
At least 16 characters with uppercase, lowercase, numbers, and symbols is a solid default. Longer passwords resist brute-force attacks better than short complex ones.
What does the strength meter measure?
It estimates entropy based on length and character variety. It is a quick guide, not a guarantee — always use unique passwords per account and store them in a password manager.
Should I exclude ambiguous characters?
Enable this when passwords might be read aloud or typed manually (Wi-Fi codes, printed handouts). For password-manager use, leaving all symbols enabled is fine.
Can I generate multiple passwords at once?
Click Generate repeatedly for new values. For bulk needs, use the Random String Generator with bulk count, or copy each password into your manager as you go.
