Random Password Generator
Build strong, unique passwords without leaving your browser. Choose the length and character types you want, generate a random password, and quickly copy or export it as a branded image if you need to share it securely.
Passwords and history are generated and stored only on this device using local storage. LifeHackToolbox never sees or stores your secrets.
Passwords are generated only in this browser.
Generated passwords are not sent anywhere and history is stored only in this browser using local storage. You are responsible for saving them in a password manager or secure location.
Settings
Quick safety notes
- Use a password manager to store generated passwords.
- Do not reuse the same strong password across multiple sites.
- For extremely sensitive accounts, use two-factor authentication in addition to a strong password.

Estimated strength
This estimate is based on length and character variety only. Real security also depends on where and how you store this password.

How this password generator works in your browser
This random password generator builds passwords entirely in your browser using JavaScript. It never sends your selections or generated values to a server. You can choose the length, toggle character classes such as uppercase, lowercase, numbers, and symbols, and optionally remove ambiguous characters like 0/O and 1/l/I to make copied passwords easier to read.
The strength meter is a simple heuristic that looks at both length and character variety. Longer passwords that use more character classes generally get a higher score. It is not a cryptographic audit, but it gives you a quick sense of whether you are in the "weak", "strong", or "very strong" range compared with common guidance.
For best results, pair this generator with a dedicated password manager. That way, you can use long, unique passwords for every account without needing to memorize them. Avoid reusing the same password across multiple sites. When possible, enable two-factor authentication so that a stolen password alone is not enough to log in.
LifeHackToolbox keeps everything privacy-first. The password history panel stores only the last few passwords in your local storage, which never leaves your device. If you clear your browser data or switch devices, that history disappears. For sharing specific secrets you might also use tools like the QR Code Generator to encode short tokens into scannable codes without leaving the browser.
This password generator fits alongside other simple utilities on LifeHackToolbox that run 100% client-side. Whether you are creating secure passwords, linting JSON, or generating QR codes, the goal is the same: fast, focused tools that do one job well and respect your data.
Why strong random passwords matter
Passwords are still the default way most websites and apps protect accounts. Short, predictable passwords are easy for attackers to guess or brute-force, especially if they reuse leaked credentials from other breaches. A strong random password is long, uses multiple character types, and avoids obvious patterns like dictionary words or keyboard walks. The goal is to make it infeasible for someone to guess or systematically try every combination in a reasonable time.
This random password generator lets you tune the character set so you can align with different site rules while still maximizing strength. You can include uppercase and lowercase letters, digits, and symbols, and optionally remove characters that are easy to misread when copying. The strength bar gives you a quick signal based on length and character variety, so you can see how changes affect the quality of the password before you use it.
Best practices for using generated passwords
For everyday accounts, security experts recommend using a password manager and giving every site a unique, randomly generated password. That way, a breach at one service does not spill over into your email, banking, or work accounts. When possible, turn on multi-factor authentication so that even if a password leaks, an attacker still needs access to a second factor, such as a hardware token or phone prompt. Avoid writing high-value passwords in plain text documents or sending them over unencrypted channels like normal email.
This tool keeps a short history of recent passwords in your browser to make it easier to recover something you just generated, but it is not intended as a long-term storage system. Once you have copied a password into your manager or secure notes, you can clear the history by wiping your browser storage or simply ignore it; it never leaves your device.
Privacy-friendly and fully client-side
Like other tools on LifeHackToolbox, this password generator runs entirely in your browser. There is no account to create and no data is sent to a remote server. That makes it suitable for work environments where you cannot paste secrets into unknown websites, and for anyone who prefers to keep sensitive data off third-party services. All of the logic for generating randomness, tracking strength, and recording recent passwords stays local.
If you need to share access or short secrets in a more visual form, you can pair this generator with tools like the QR Code Generator to encode tokens into scannable codes, or developer-focused utilities such as the JSON Linter & Formatter when you are working with API keys and structured config. The aim is to provide a small set of focused, privacy-first tools you can trust to run right in your browser.
