Frequently Asked Questions — Random String Generator
How random are the generated strings?
The tool uses the Web Crypto API, which provides a cryptographically secure random number generator built into your browser. The generated strings are suitable for tokens, identifiers, and test data. For critical security applications, always use dedicated security libraries.
Can I specify exactly which characters to include?
Yes. In custom mode, you can enter the exact set of characters you want the generator to pick from. For example, if you only want vowels, enter "aeiou" and the generated string will use only those five characters.
Can I generate multiple strings at once?
Yes. Set the quantity field to any number and the tool will generate that many unique random strings at once. Each string is displayed on its own line and you can copy all of them together or individually.
