Password Security Tips
Length Over Complexity
A 16-character passphrase like "correct-horse-battery-staple" is stronger and more memorable than "P@ssw0rd!23". Aim for 14+ characters.
Use a Password Manager
Generate and store unique, strong passwords for every account. A password manager is the single best security investment you can make.
Never Reuse Passwords
Credential stuffing attacks rely on password reuse. If one service is breached, attackers try those credentials on other services.
Enable MFA Everywhere
Multi-factor authentication adds a second layer of protection. Even if your password is compromised, MFA can block unauthorized access.
