  3. Click "Start generating". The random codes appear in the output box.
  4. Copy the result or export it as TXT.

FAQ

Q: Can I customize the character set?

A: Yes. Any character works — for example, remove ambiguous characters, add symbols, or use only digits.

Q: Are the generated codes guaranteed to be unique?

A: Uniqueness is not guaranteed. With a large count, duplicates can appear — pair this with the "Remove Duplicates" tool to clean up.

Q: Is any data uploaded while generating?

A: No. Everything is generated locally in your browser; nothing touches the network.
