What makes a strong password?

Length

At least 16 characters. Every extra character multiplies crack time exponentially.

Randomness

Avoid real words and patterns. True randomness is what makes a password hard to guess.

Character variety

Mix uppercase, lowercase, digits, and symbols to maximize the search space.

Uniqueness

Never reuse passwords. Use a password manager to store a unique one for every account.
