Securing your online accounts with strong, unique passwords is more important than ever. Weak or reused passwords leave sensitive information vulnerable to hackers who can easily exploit it through phishing attacks or data breaches.

Up your password game by creating passwords that are hard to crack, resisting the impulse to reuse them, and using multifactor authentication as an extra layer of protection.

Create longer, stronger passwords/phrases

Weak passwords are easy for computers or people to guess. To make passwords stronger, combine at least 12-16 upper- and lowercase letters, numerals, and special characters. Avoid guessable information like birthdays or names of pets.

Or consider a passphrase, a string of words that’s easier to remember and harder for computers to crack. (Note that many systems require any password or passphrase to combine different kinds of characters.)

Use unique passwords for each account

Reusing passwords across multiple accounts leaves you vulnerable to data breaches—a crook who steals your password for one service can use it to access others. To limit potential damage, give each of your accounts a unique password.

A password manager application can help you generate, store, and share passwords across devices. It reduces the need to memorize or look up strong passwords.

Always use multifactor authentication

Multifactor authentication (MFA) provides an extra layer of protection by requiring a code sent via text or a response to an authentication app to confirm system logins. They prevent unauthorized users from logging into your accounts with stolen credentials.

Two-Step Login/Duo is the University of Iowa’s MFA system. Your bank, social media platforms, and online services might offer their own MFA tools. Always enable them when available.

By following these simple steps, you can take control of your account security and greatly reduce the risk of unauthorized access, protecting your personal, academic, or professional data.
