Question 1

Is the random string generator cryptographically secure?

Accepted Answer

Yes. The tool uses the browser's built-in crypto.getRandomValues() API which provides cryptographically strong random numbers suitable for tokens, IDs, API keys and one-time passwords.

Question 2

Can I generate multiple strings at once?

Accepted Answer

Yes. Use the Count field to generate up to 1000 strings in a single click. Each one is independently generated with the same selected character set and length.

Question 3

What character sets are supported?

Accepted Answer

You can enable or disable uppercase letters, lowercase letters, digits and symbols independently. At least one set must be enabled. A custom character set is also supported.

Question 4

What can I use these random strings for?

Accepted Answer

Passwords, API keys, session tokens, voucher codes, file names, default salts, test data, anonymous identifiers and anywhere else you need unpredictable strings.
