Username Generator
This username generator creates 5 random ideas at once, from a themed word category or your own keyword, with an optional number or leetspeak styling. Good for a new account where you want something available and not tied to your real name — a username isn't a secret the way a password is, so this tool optimizes for originality, not entropy.
If you enter a word, it's paired with a random word instead of two random words.
crypto.getRandomValues(), the Web Crypto API's cryptographically secure random source. The category
lists are separate fixed word sets by theme; typing your own keyword swaps one half of the pair for your
word instead of a random one. The "Check GitHub / Reddit / Instagram" links next to each result just open
that profile URL in a new tab so you can look for yourself — this page can't check availability
automatically, since that would require querying each platform's servers directly, which their sites don't
allow from a page like this one. There's no entropy claim here because a username's job is to be unique and
available, not to resist guessing the way a password does.
A username isn't a password
Usernames are usually public or semi-public, shown next to your posts or displayed to other users — they're an identifier, not a secret. Don't reuse a generated username as a password, and don't treat a hard-to-guess username as a substitute for a real password on the same account.
Frequently asked questions
Will this username be available on every platform?
There's no way to guarantee availability across every site from here — use the "Check GitHub / Reddit / Instagram" links next to each result to look it up directly, or regenerate for a new batch of five.
Should I use my real name in a username?
That's a personal choice, but a random username avoids linking an account to your identity, which matters more on some platforms than others.
Is a leetspeak username more secure?
Not meaningfully — leetspeak substitution here is a styling choice, not a security measure. Use a real password generator for anything that needs to resist guessing.
What does the word category change?
It swaps which fixed word list the generator draws from — Animals, Space, Gaming, Food, or Nature instead of the general mix. Pick whichever fits the platform or vibe you're going for.
How does the custom keyword option work?
Type a word and it replaces one half of the pair, so you get your word combined with a random one instead of two random words. Leave it blank to get two fully random words.
