Quick Summary

"Weak passwords are the #1 entry point for data breaches. Learn how to generate cryptographically strong passwords and check their strength locally without leaking them to a server."

Is your password 'Password123'? If so, you are a target. Secure your digital identity with entropy-based passwords.

1. The Math of Digital Defense

A strong password isn't just 'hard to guess'; it is mathematically expensive to crack using brute-force attacks.

  • Include symbols and numbers to increase entropy.
  • Aim for 16+ characters for critical accounts.
  • Avoid common patterns like 'qwerty' or '12345'.
Length is often more important than complexity. A 20-character phrase is harder to crack than an 8-character symbol mix.

2. Browser-Native Security

Never send your potential passwords to a third-party server. Even if the connection is HTTPS, a server-side log could store your secret.

  • Generate keys locally in RAM.
  • Check strength with zero network requests.
  • Ensure true randomness using crypto-APIs.
IteraSuite uses the window.crypto API for enterprise-grade randomness in the browser.
