Lesson 2

Random Passwords

What good randomness means and why crypto APIs matter.

A generated password is only as good as its random source. For real secrets, use cryptographic randomness from the platform, not ordinary pseudo-random helpers intended for UI effects or games.

Good random passwords are useful for:

  • Password manager entries
  • Temporary admin credentials
  • Test users and seed data
  • One-time handoff secrets

Do not send generated passwords through chat or email if the account is important. Use a password manager, secret manager, or secure sharing feature.
