Original: Stop Using 'password123': A Developer's Guide to Strong Passwords

Short summary

A developer's guide explaining that password length matters more than character variety, with 16+ character passwords being effectively uncrackable. It recommends using crypto.getRandomValues() for true randomness rather than human-chosen patterns, and provides specific recommendations for API keys, database passwords, and Wi-Fi passwords. The post includes promotion of the author's free password generator tool.

  • Length is the biggest password strength factor — 16+ chars lowercase beats 8 chars with symbols
  • Use crypto.getRandomValues() for cryptographically secure random password generation
  • Specific recommendations: 32-64 char API keys, 20+ char database passwords, never reuse passwords

Generated with AI, which can make mistakes.

Is this a good recommendation for you?
