Password Generator
Create strong random passwords and passphrases in your browser. Tune length, symbols, and ambiguity, then copy once. Generation uses local randomness and never phones home. A private generator for accounts, test users, and sharing secrets over a side channel you control.
Runs in your browser. Nothing is uploaded.
About this tool
Build passwords from uppercase, lowercase, digits, and symbols, with an option to drop ambiguous 0/O/I/l/1. Generate a single secret or a bulk list. A simple entropy meter estimates bits as length × log2(charset size) so you can see when a short charset is too weak.
How to use: set length and charset toggles, generate, copy once. Randomness comes from crypto.getRandomValues, not Math.random. Use the bulk list for test users; do not email a list of real production passwords.
Example: length 20 with all classes and no ambiguous characters is a typical personal secret. The random-string tool is better for opaque API tokens that will never be typed.
We do not store generated passwords. After the first load you can keep generating offline. Nothing is phoned home. Copy once and paste into your password manager; refreshing the page draws a new value. Related: random string for nonces, UUID generator for identifiers that are not meant to be typed.

UUID Generator
Generate RFC 4122 UUIDs (v4 and v7) in bulk, or validate and reformat pasted IDs. Copy a list for database seeds, test fixtures, and idempotency keys. Uses the Web Crypto RNG so IDs are created on-device with no telemetry.
Random String Generator
Generate random alphanumeric strings with a charset and length you choose. Handy for tokens, test IDs, and dummy keys. Uses local randomness so generated values are not logged by a hosted generator.
Random JSON Generator
Generate nested JSON fixtures for mocks and tests. Tune depth and item count, then copy a valid object or array. Built with the Web Crypto RNG so dummy payloads are created on-device.
Random Number Generator
Pick random integers or decimals in a min–max range, one at a time or in a list. Simple test data and dice-style rolls without a remote RNG. Generated on your device.
QR Code Generator
Encode a URL or any text as a QR code in the browser. Tune error correction, size, and colors, then download PNG or SVG. Encoding stays on the device. There is no QR API.
