What is password entropy?
Entropy measures unpredictability in bits. It's log₂(poolSize^length). 128 bits is considered unbreakable with current technology. Every extra character multiplies combinations.
Why passphrases work
4 random words from a 7,776-word list give ~51 bits of entropy — more than most 8-character passwords. They're also far easier to type and remember.
Never reuse passwords
A breach at one site exposes all accounts using the same password. A password manager + unique passwords per site is the single best security improvement you can make.
Ambiguous characters
O (letter) vs 0 (zero), I vs l vs 1 — these look identical in many fonts. Excluding them prevents mistyping, especially for passwords you'll type rather than paste.
