Is this username generator safe and private?

Yes. The tool runs 100% in your browser and uses the Web Crypto API (window.crypto.getRandomValues) for randomness. No usernames, prefixes, or inputs are ever sent to a server, so your ideas stay completely private.

Will the generated usernames be unique and available?

Every batch is generated locally with cryptographically secure randomness and automatic de-duplication, so the usernames within a batch are unique. However, popular platforms may already have taken a name — if one is unavailable, simply generate again or tweak the prefix, separator, or number length.

Can I use these usernames on Instagram, TikTok, Xbox, or Discord?

Yes. The generator produces handles compatible with most platforms. Keep in mind each service has its own rules (for example, Instagram allows letters, numbers, periods, and underscores), so pick a separator and options that match the platform you are signing up for.

What is leetspeak (1337) mode?

Leetspeak replaces letters with visually similar numbers and symbols, for example turning "cool" into "c00l" or "tiger" into "7ig3r". It is popular in gaming and retro internet culture and can help you find a username that is more likely to be available.
