Random String Generator
Generate random strings
Frequently Asked Questions
How does the Random String Generator work?
Specify the length and character set (uppercase, lowercase, numbers, symbols), and the generator creates a cryptographically random string. It uses the Web Crypto API (crypto.getRandomValues) for true randomness.
Can I generate a secure password with this tool?
Yes. Set length to 16+ characters and include all character types (uppercase, lowercase, numbers, symbols). A 16-character password with all types has approximately 10^30 possible combinations, making brute force infeasible.
How do I generate multiple random strings at once?
Set the quantity (up to 100) and the generator creates multiple unique strings. Each string is independently random. Results can be copied individually or all at once, separated by newlines.
Can I exclude ambiguous characters?
Yes. Enable "exclude ambiguous" to remove characters that look similar: 0/O, 1/l/I, 5/S, 2/Z. This is useful for generating codes that humans need to read and type, like license keys or verification codes.
Is the random generation truly random?
Yes. The generator uses the Web Crypto API which provides cryptographically secure pseudo-random numbers. This is suitable for security-sensitive applications like API keys, tokens, and passwords.
