How does the random password generator work?

Our random password generator uses the Web Crypto API's cryptographically secure pseudo-random number generator (CSPRNG). This ensures each character is selected with true randomness, making passwords impossible to predict or reverse-engineer.

Why is randomness important in passwords?

True randomness eliminates patterns that hackers exploit. Human-created passwords often contain predictable elements like names, dates, or keyboard patterns. Random passwords have no such weaknesses, making them exponentially harder to crack through dictionary attacks or pattern recognition.

Is the random password generator truly random?

Yes, we use cryptographically secure pseudo-random number generation (CSPRNG) provided by your browser's Web Crypto API. This is the same level of randomness used in encryption and financial security systems, providing true unpredictability.

Are randomly generated passwords stored anywhere?

No. All password generation happens entirely in your browser using JavaScript. Your random passwords are never transmitted to any server or stored online. Only you have access to your generated passwords.

How Our Random Password Generator Works

Cryptographically Secure Random Number Generation

Our random password generator uses the Web Crypto API, specifically the crypto.getRandomValues() function. This provides cryptographically secure pseudo-random numbers (CSPRNG) that are:

Unpredictable: Cannot be guessed even with knowledge of previous outputs
Non-reproducible: Same inputs never produce same outputs
Statistically uniform: Each character has equal probability

Why True Randomness Matters

Standard random number generators (like Math.random()) are predictable and unsuitable for security. Our CSPRNG-based approach ensures:

No patterns that attackers can exploit
No seed values that can be guessed
Maximum entropy (randomness) per character

Privacy by Design

All random generation happens locally in your browser. Your passwords never leave your device - we never see, store, or transmit them. This is verified by our open-source JavaScript code.

Random vs Human-Created Passwords

Human-Created (Weak)

Based on dictionary words
Contains personal info (names, dates)
Uses predictable substitutions (@ for a)
Follows keyboard patterns (qwerty)
Reused across multiple accounts

Example: P@ssw0rd123!

Random Generated (Strong)

No dictionary words
No personal information
True random character selection
No recognizable patterns
Unique for every account

Example: kX9$mR2@vL5#nQ8&
