Yes. This tool uses the browser's built-in Crypto.getRandomValues() API for cryptographically secure random numbers, not Math.random() pseudo-random numbers. Generated strings are suitable for temporary passwords, session tokens, API keys, and other security-sensitive scenarios.
Fully customizable. Preset options include: uppercase letters (A-Z), lowercase letters (a-z), digits (0-9), special symbols (!@#$%^&* etc.). Any combination can be selected, and custom character sets can be manually entered for maximum flexibility.
This feature excludes easily confused characters like 0/O, 1/l, 8/B, etc. Enabling it significantly improves string readability and manual input accuracy. Perfect for generating verification codes or passwords that need to be entered by hand.
