FAQ
Why are 0O1lI missing from the default charset?
They are easily confused visually (0/O, 1/l/I); excluding them avoids transcription errors. Add them back via the custom charset if needed.
Are the strings cryptographically secure?
This tool targets test data and numbering using Math.random; for high-security secrets use our password generator built on crypto-grade randomness.
Will my data be uploaded?
No, all generation runs locally in your browser.
