Grey, White, and Black passwords

In the GreyPass lexicon — shared with this school — passwords sit on a spectrum of light:

• White — already in cracked lists (123456, password). Machines guess them instantly.
• Black — pure high-entropy randomness. Strong, but humans cannot memorize them without a vault.
• Grey — memorable structure with enough entropy to resist online guessing. The sweet spot between Elvish verse and Mordor noise.

“Brightness” rises when a grey password is reused often enough to drift toward white. Prefer unique greys, or black keys stored offline / in a vault such as VIP.passkey.vip.
