Question 1

How to generate a secure password?

Accepted Answer

Use cryptographically secure random number generator (CSPRNG), not Math.random(). Include: 16+ characters, uppercase, lowercase, numbers, symbols. Avoid: dictionary words, personal info, patterns. Our tool uses Web Crypto API (window.crypto.getRandomValues) for true randomness. Generate unique password per account. Store in password manager. Verify strength using entropy calculator. Longer = better (20+ chars ideal).

Question 2

What is a cryptographically secure generator?

Accepted Answer

Cryptographically secure pseudo-random number generator (CSPRNG) produces unpredictable random values suitable for security. Uses entropy from OS (hardware noise, timing). Not guessable like Math.random(). Examples: Web Crypto API, /dev/urandom, CryptGenRandom. Essential for passwords, encryption keys, tokens. Standard random generators are predictable - never use for security. CSPRNG passes statistical randomness tests.

Question 3

Should I use memorable or random passwords?

Accepted Answer

Random passwords (CSPRNG-generated) are strongest - maximum entropy, no patterns. Memorable passwords (passphrases) are easier to remember but slightly weaker. Best approach: random passwords in password manager (most accounts) + memorable passphrase for master password. Example passphrase: "Tiger!Climb$Forest29". Avoid: common phrases, song lyrics, quotes. Use password manager to eliminate memorization need for most accounts.

Question 4

Is it safe to use online password generators?

Accepted Answer

Yes, if using client-side CSPRNG (no server transmission). Our tool generates passwords in your browser - never sent to server. Check: uses crypto.getRandomValues(), open-source code, HTTPS. Avoid: generators requiring server requests, closed-source tools, non-HTTPS sites. Most secure: offline generator or password manager. Clear clipboard after copying. Never save generated passwords in browser autofill without master password.

Question 5

What length should my password be?

Accepted Answer

Minimum 16 characters for strong security. Longer = exponentially stronger. Recommendations: 16 chars (good), 20 chars (better), 32 chars (excellent for high-value accounts). Master passwords: 20-30 chars (passphrases). Short passwords (<12 chars) are vulnerable to brute-force. Each added character increases cracking time exponentially. Modern systems support 64+ characters. Use maximum allowed length for critical accounts.

Question 6

Should I include special characters?

Accepted Answer

Yes, if allowed. Special characters (!@#$%^&*) increase entropy and character space. Some systems limit allowed symbols - check requirements. Avoid ambiguous characters (O/0, I/l/1) if typing manually. Balance: length matters more than character variety. 20 char lowercase > 10 char with all types. Best: 16+ chars with uppercase, lowercase, numbers, and symbols. Use password manager to handle complex passwords.

Question 7

How to remember generated passwords?

Accepted Answer

Do not try - use password manager instead. Password managers: store encrypted passwords (AES-256), auto-fill credentials, sync across devices, generate unique passwords. Recommended: Bitwarden, 1Password, LastPass, KeePass. Exception: master password - use memorable passphrase (20+ chars). Write master password on paper, store in safe. Enable MFA on password manager. Better to store securely than use weak memorable passwords.

Question 8

Can generated passwords be cracked?

Accepted Answer

Properly generated passwords (16+ chars, true random, CSPRNG) take centuries to crack with current technology. Weak points: password reuse, phishing, keyloggers, compromised password manager. Quantum computers (future) threaten current encryption - use 32+ chars for future-proofing. Defense: unique passwords per account, MFA, breach monitoring, regular security audits. No password is uncrackable - layer security with MFA.
