Frequently Asked Questions
What character sets can I use?
You can choose from lowercase letters, uppercase letters, digits, and symbols, in any combination. Restricting to alphanumeric is useful for tokens that need to work in URLs or filenames.
How is the randomness generated?
The generator uses the Web Crypto API (crypto.getRandomValues), which provides cryptographically secure randomness — suitable for generating API keys, session tokens, and secrets.
Can I generate multiple strings at once?
Yes. You can specify a count and get multiple random strings in a single operation, one per line, ready to copy.
