Password Security Guide — Create and Manage Strong Passwords

Why Password Security Matters

Passwords remain the primary way we protect our online accounts. According to security research, compromised credentials are involved in over 80% of data breaches. Strengthening your password practices is one of the most impactful things you can do for your security.

What Makes a Strong Password?

A strong password should be:

Long — At least 16 characters (the longer, the better)
Unique — Different for every account
Complex — A mix of uppercase, lowercase, numbers, and symbols
Random — Not based on personal information or dictionary words

The Passphrase Approach

An effective alternative to complex passwords is the passphrase method. Combine four or more random, unrelated words to create a memorable but secure password. For example, "correct horse battery staple" is both memorable and strong.

Common Password Mistakes

Avoid these common mistakes that make passwords easy to crack:

Using personal information (birthdays, pet names, addresses)
Simple keyboard patterns (qwerty, 123456, password)
Single word with basic substitutions (p@ssw0rd)
Reusing the same password across multiple sites
Writing passwords on sticky notes

The Case for Password Managers

It is humanly impossible to remember unique, strong passwords for dozens of accounts. Password managers solve this by storing all your credentials in an encrypted vault protected by one master password.

Benefits include automatic password generation, secure sharing with family members, breach monitoring and alerts, and autofill across browsers and devices.

Two-Factor Authentication

Even the strongest password can be compromised through phishing or data breaches. Two-factor authentication adds a second verification step, dramatically reducing the risk of unauthorized access.

We recommend using an authenticator app over SMS for 2FA, as SMS codes can be intercepted through SIM swapping attacks.

Take Action

Start by installing a password manager and changing the passwords on your most critical accounts — email, banking, and social media first. Then gradually update the rest of your accounts over time.
