Frequently Asked Questions
Are the generated strings cryptographically secure?
Yes, this tool uses the Web Crypto API (crypto.getRandomValues) which provides cryptographically secure random number generation.
How long should a secure password be?
At least 12-16 characters for most purposes, using a mix of uppercase, lowercase, numbers, and symbols. For critical systems, 20+ characters are recommended.
Can I exclude ambiguous characters?
Yes, you can exclude characters that look similar (like 0/O, 1/l/I) to avoid confusion when manually typing generated strings.
