Why Use a Random Password Generator?
Strong & Unpredictable
Our password generator uses cryptographically secure random number generation (CSPRNG) to create truly random passwords that are virtually impossible to guess or crack using brute force attacks.
Customizable Security
Choose from quick presets for different use cases (Banking, Social Media, Gaming) or customize every aspect including length, character types, and whether to exclude ambiguous characters for easier typing.
Instant Analysis
Every generated password comes with an instant entropy analysis showing its strength. See expected crack times and get real-time feedback on password security.
Batch Generation
Generate multiple passwords at once (up to 20) and export them for use across different accounts. Perfect for IT administrators setting up multiple user accounts.

Password Security Glossary
- Entropy
- A measure of password randomness in bits. Higher entropy means more secure and harder to crack. Our tool calculates entropy based on character set size and password length.
- Character Set
- The pool of characters (lowercase, uppercase, numbers, symbols) used to generate passwords. Larger character sets exponentially increase password security.
- Brute Force Attack
- A method where attackers systematically try every possible password combination until finding the correct one. Strong passwords make this computationally infeasible.
- Pronounceable Password
- A password designed to follow phonetic patterns (alternating consonants and vowels), making it easier to remember and communicate verbally.
- Ambiguous Characters
- Characters that look similar such as 0 (zero) and O (letter O), or 1 (one) and l (lowercase L). Excluding them prevents typing confusion.
- CSPRNG
- Cryptographically Secure Pseudo-Random Number Generator. Our tool uses Web Crypto API's CSPRNG for maximum password security.
Frequently Asked Questions about Random Password Generator
To create a strong random password, use at least 12 characters combining uppercase letters, lowercase letters, numbers, and symbols. Our generator uses cryptographic randomness to ensure maximum security. For critical accounts like banking, use 16+ characters with all character types.
