Quick answers about tools, privacy, formatting, and common issues.
GeneGator is a lightweight collection of generator tools designed to create useful outputs quickly—passwords, UUIDs/ULIDs, random numbers, and more. The focus is speed, minimal UI, and simple export options.
No. Tools are available without registration. We keep the experience simple: open a tool, generate, copy/export, done.
Use the Tools page search box. You can also filter by category tags. If you know the tool URL, you can directly open it under /tools/<tool-name>.
By default, our tools are designed to run in your browser, and generated outputs remain on your device. We do not ask you to log in or submit generated values to the server unless a future tool explicitly requires server processing (and will be clearly stated).
Yes—password generation uses the browser’s cryptographically secure random generator (window.crypto.getRandomValues), not Math.random(). This is the recommended approach for secure randomness in modern browsers.
For most users, a 16–20+ character password with a mix of letters, numbers, and symbols is strong. For very high security needs, prefer longer passwords (24–32+) or passphrases, and store them in a reputable password manager. Always follow your organization’s policies.
Ambiguous characters (like 0/O/o and 1/l/I) can be misread when typing or sharing. Avoiding them reduces mistakes, especially for manual entry.
If enabled, the generator guarantees at least one character from each enabled group (uppercase, lowercase, digits, symbols). This helps meet password policy requirements.
It prevents patterns like “aa” or “11” appearing back-to-back. This is mostly a usability preference; the security impact is minor compared to using longer passwords.
If you enable uniqueness constraints (or heavy exclusions) the generator may not be able to produce the requested count without repeating values. Reduce exclusions, increase length, or disable uniqueness-related constraints.
UUID v4 is random and widely used. UUID v7 is time-ordered (good for database indexing and sorting by creation time). UUID v5 is deterministic: the same namespace + name always yields the same UUID (useful for stable identifiers derived from inputs).
ULID is a 26-character, URL-friendly identifier that is sortable by time. It’s great when you want identifiers that sort roughly by creation time and are easy to use in URLs.
Classic UUID v1 uses a MAC address / node ID and clock sequence. Browsers can’t access MAC addresses for privacy reasons. Our v1 option is a standards-shaped, time-influenced ID suitable for many uses, but if you require strict RFC-compliant v1 semantics for interoperability, generate v1 server-side in your backend stack.
Random UUIDs can cause index fragmentation in some databases when used as primary keys. Time-ordered UUIDs (like v7) tend to insert more sequentially, which can be friendlier for indexes—especially at scale.
It uses window.crypto.getRandomValues() for randomness. That’s suitable for most use cases like selection, sampling, and secure-ish tokens. For strict cryptographic protocols, use purpose-built libraries and your security team’s guidance.
Unique means no repeats in the list. It can fail if the range is too small (e.g., requesting 100 unique integers between 1 and 50) or if you exclude too many values. Increase the range or reduce the quantity.
Instead of uniform randomness, values cluster more around the middle of the range—useful for simulations and sampling where you want fewer extremes.
Most tools support Copy, Copy List (bulk), and Download .txt. Use these for quickly moving results into spreadsheets, notes, or code.
Different systems expect different formats. Some frameworks use {braces}, some APIs use urn:uuid:, and some databases store UUIDs without hyphens.
Clipboard access can be blocked by browser permissions or non-HTTPS contexts. Ensure you are on HTTPS. If it still fails, try a different browser or copy manually from the output box.
If something becomes unreadable, it usually means a Bootstrap component needs a dark override. Tell us which tool and section, and we’ll adjust the theme variables or add a small CSS fix.
We prioritize tools that are broadly useful, fast to use, and easy to validate (utilities, converters, formatters). If you have a suggestion, send it via Contact.
