Frequently Asked Questions
Common questions about the free online username generator.
Pick a word style and separator, then click generate and a batch of ideas appears with a
number and a length check.
No. The tool only builds ideas that look reasonable. You still need to check availability on
the site you want to join.
It checks the length window you set and that the name only uses lowercase letters, digits,
dot, underscore and hyphen.
The length filter may be too narrow, so relax the minimum or maximum and generate another
batch.
It swaps letters for similar looking digits, so swift becomes 5w1f7, which many sites still
accept.
Many sites allow it, but some require a letter first. Regenerate without a number suffix if
you are unsure.
They are random combinations, but popularity varies. Adding a number suffix makes a clash far
less likely.
No. Word lists and random numbers stay in your browser, and the tool never contacts any
website.
Yes. The generator is fully responsive and works on phones, tablets and desktop computers.
