Frequently Asked Questions
What types of random data can I generate?
Our random generator supports five main categories: random numbers (integers, decimals, binary, hexadecimal), random strings (customizable character sets), secure passwords (with various complexity options), random lists (names, colors, animals), and test data (emails, phone numbers, dates, URLs).
How secure are the generated passwords?
Our password generator uses cryptographically secure random number generation to create strong, unpredictable passwords. You can customize length (4-64 characters) and include uppercase letters, lowercase letters, numbers, and symbols for maximum security.
