FAQ
Are these strings truly random?
Yes, this tool uses the Web Crypto API (crypto.getRandomValues) which provides cryptographically secure random numbers, making the output suitable for passwords and tokens.
Can I use this for passwords?
Yes. For strong passwords, we recommend using a length of at least 16 characters with all character sets enabled (uppercase, lowercase, digits, and symbols).
What is the custom character set for?
The custom character set lets you define exactly which characters should appear in the generated strings. This is useful when you need strings with specific characters only.
