Password Security Guide
Learn best practices for password security, how to create strong passwords, and how to protect your online accounts.
Password Security Best Practices
Your password is the first line of defense for your online accounts. Following these best practices can significantly reduce your risk of being hacked.
Use a unique password for every account
Never reuse passwords across different sites. If one site gets breached, all your accounts using that password become vulnerable.
Make passwords long (12+ characters)
Length is the most important factor in password strength. A 12-character password is exponentially harder to crack than an 8-character one.
Use a mix of character types
Combine uppercase letters, lowercase letters, numbers, and special characters to maximize entropy.
Change passwords when necessary
While frequent password changes are no longer universally recommended, you should immediately change any password that you know or suspect has been compromised.
Enable Two-Factor Authentication (2FA)
2FA adds a second layer of security beyond just your password. Even if someone gets your password, they cannot access your account without the second factor.
How to Create Strong & Memorable Passwords
A strong password doesn't have to be impossible to remember. Try these techniques:
Passphrase method
Combine 4-6 random words to create a long but memorable password: "correct horse battery staple". This is both strong and easy to type.
correct horse battery stapleSentence-based patterns
Turn a sentence you can remember into a password: "My first dog was named Buddy in 2020!" → MfdwnBi2020!

Password managers can generate and store strong, unique passwords for every account. You only need to remember one master password.
Two-Factor Authentication (2FA)
2FA significantly increases your account security by requiring a second verification method in addition to your password.
🔐 Authenticator Apps (TOTP)
Apps like Google Authenticator, Authy, or Microsoft Authenticator generate time-based one-time codes. These are more secure than SMS-based 2FA.
📱 SMS/Text Message Codes
Codes sent via SMS are convenient but vulnerable to SIM-swapping attacks. Prefer authenticator apps when possible.
🔑 Hardware Security Keys
Physical keys like YubiKey or Google Titan Key provide the highest level of security. They are resistant to phishing and require physical possession of the device.
⚠️ Always set up recovery codes
When enabling 2FA, save the recovery codes in a secure place. These codes are your backup if you lose access to your 2FA device.

Built-inWhat to Do After a Data Breach
If you discover one of your passwords has been leaked in a data breach, act immediately:
- Change the compromised password immediately
Use our Password Generator to create a strong, unique replacement.
- If you used this password elsewhere, change it on those sites too
This is why unique passwords per site are critical.
- Enable 2FA on the affected account and other important accounts
- Monitor your accounts for suspicious activity
Check for unauthorized logins, password reset emails, or unfamiliar transactions.
- Consider freezing your credit if financial information was exposed
A credit freeze prevents criminals from opening new accounts in your name.
