Frequently asked questions

Can I choose which characters to include?

Yes. You can configure the character set to include uppercase letters, lowercase letters, numbers, and symbols individually.

Is the generated string cryptographically secure?

Browser-based random string generation uses the JavaScript Math.random function which is not cryptographically secure. For security-sensitive tokens, use a server-side generator.

Is there a maximum length?

You can generate strings up to a reasonable length. Very long strings may be slow to generate.
