What makes a password strong
Length matters more than complexity alone. A 16-character password with mixed character types resists brute-force attacks far better than an 8-character password with symbols. Never reuse passwords across sites.
Store passwords safely
Copy generated passwords directly into a password manager such as 1Password, Bitwarden, or Apple Keychain. Avoid saving them in plain-text notes or screenshots.
