How to Generate a Strong Password
A truly strong password requires three foundational criteria: it must be long (16+ characters), unpredictable, and unique across every service you use.
The FaxCore password generator uses the browser native Web Crypto API (crypto.getRandomValues()) with rejection sampling. This ensures true uniform randomness with zero modulo bias, making brute-force guessing mathematically infeasible.
How Secure Is Your Password?
Approximate brute-force crack times at 10 billion guesses per second:
| Length | Character Types | Time to Crack |
|---|---|---|
| 6 chars | Lowercase only | Under 1 second |
| 8 chars | Mixed case + numbers | ~3 hours |
| 10 chars | Mixed case + numbers + symbols | ~5 years |
| 12 chars | Mixed case + numbers + symbols | ~34,000 years |
| 16 chars | Mixed case + numbers + symbols | ~1 trillion years |
| 20 chars | Mixed case + numbers + symbols | ~63 quintillion years |
Password vs. Passphrase: Which Should You Use?
Both methods protect your digital accounts, but they serve different security needs:
Random Passwords
Best for: Everyday website logins, SaaS accounts, and mobile apps managed with a password vault.
A random password uses a dense mixture of uppercase, lowercase, numbers, and symbols. It packs maximum mathematical entropy into a compact 16+ character string, satisfying strict complexity requirements on legacy portals.
Cryptographic Passphrases
Best for: Master passwords, device encryption, PIN overrides, and credentials you type manually.
A passphrase combines multiple dictionary words (such as Dragon-Rocket-Galaxy-42). Because passphrases are longer, they deliver equal or greater cryptographic entropy against brute-force attacks while remaining far easier to memorize and type accurately.
Frequently Asked Questions
Random password generators use cryptographically secure random number generators (CSPRNG), like the Web Crypto API, to draw uniformly distributed characters from your chosen sets (uppercase, lowercase, numbers, symbols). This completely avoids predictable human keyboard walks and dictionary words.
Yes, provided the tool executes 100% on the client side. The FaxCore password generator runs entirely in your browser JavaScript engine. It does not send your generated passwords over the network or log them anywhere.
A passphrase combines multiple random words (such as Dragon-Rocket-Galaxy-42). Because passphrases are longer, they deliver exceptional cryptographic entropy while remaining significantly easier for human memory. They are ideal for master passwords and disk encryption.
Yes. Using unique, 16+ character passwords for every account prevents credential stuffing attacks. A password manager eliminates the burden of memorization while keeping your vault encrypted with zero-knowledge architecture.
Password Security Best Practices
Enable Multi-Factor Authentication (MFA)
Always pair strong passwords with hardware security keys or authenticator apps for defense-in-depth against credential theft.
Deploy an Enterprise Password Manager
Ensure teams never store credentials in plain text, spreadsheets, or shared chat channels.
Zero Credential Reuse
Never reuse work credentials on personal sites. A breach of a third-party forum should never jeopardize corporate systems.
