Random Generator Deluxe is a lightweight, privacy-friendly tool for creating strong passwords and true random numbers right in your browser. It’s designed for everyday users and power users alike: quick to use, easy to trust, and pleasant to look at.
Highlights at a Glance
- Two tools, one widget: a password generator and a single random-number generator.
- Instant strength feedback: a live meter that reacts as your password changes.
- Fully client-side: nothing leaves your device; no servers, no tracking.
- Mobile-ready UI: responsive layout with accessible labels and large tap targets.
Password Generator Features
- Length control: choose from 8–40 characters; the sweet spot for most accounts is 14–20.
- Character sets: toggle uppercase, lowercase, numbers, and symbols.
- Guaranteed diversity: when a set is enabled, at least one character from that set is injected.
- Copy in one click: the result field is read-only to avoid accidental edits, and a copy button confirms success.
- Live strength meter: labels (Weak/Medium/Strong/Excellent) update based on length and variety.
Random Number Features
- Flexible ranges: set minimum and maximum; the tool swaps them automatically if entered backwards.
- Integers and decimals: works with whole numbers and floats; floats are displayed up to 4 decimals.
- Gentle validation: helpful messages prompt for valid inputs when needed.
How It Works
When you click Generate, the app builds a pool of characters from your selections (A–Z, a–z, 0–9, symbols). It injects at least one character from each chosen set, then fills the remaining length by sampling randomly from the pool. Finally, it shuffles and trims to the exact length so you always get a balanced, properly sized password.
The strength meter scores length and diversity (uppercase, lowercase, digits, symbols). More variety and more length mean a higher score. It’s a friendly guide—not a substitute for unique passwords and 2-factor authentication.
Security & Privacy Notes
- Local-only: generation runs in your browser; no network requests are required.
- Clipboard use: the copy action writes the value to your clipboard only when you ask it to.
- Best practice: use a different password for every site and enable MFA wherever available.
- Storage: avoid saving raw passwords in notes; prefer an encrypted password manager.
Accessibility & UX
- Readable controls: clear labels, visible focus states, and consistent button sizing.
- Keyboard-friendly: sliders, checkboxes, and tabs are navigable with the keyboard.
- Status messages: copy success and validation hints are concise and noticeable.
Performance Considerations
- Small footprint: minimal CSS and vanilla JavaScript keep load times snappy.
- No dependencies: fewer moving parts; faster, safer, and easier to embed anywhere.
Usage Tips
- Pick your length (start at 16+ for important accounts).
- Enable all character sets unless a service has restrictions.
- Generate, check the strength meter, and regenerate if needed.
- Copy and save the password to your password manager.
FAQ
Is this “true” randomness?
The generator uses the browser’s JavaScript runtime. For typical password use, this is sufficient. If you need cryptographic-grade randomness for research or lotteries, use a system-provided CSPRNG or a hardware RNG.
What length should I choose?
Aim for 14–20 characters for general accounts and 20+ for high-value targets like email, cloud storage, and finance.
Do symbols always make passwords stronger?
Symbols increase search space, which helps. But length and uniqueness matter more. A long, unique passphrase can be stronger than a short mixed-character password.
