Check & Fix Reused Browser Passwords

TL;DR

Using the same password on multiple websites is risky. If one site gets hacked, all your accounts are vulnerable. This guide shows you how to check for reused passwords in your browser and what steps to take to improve your security.

Checking for Reused Passwords

1. Google Chrome:
   • Type chrome://settings/passwords into the address bar and press Enter.
   • Click on the three dots (menu) in the top right corner, then select ‘Password Checkup’.
   • Chrome will scan your saved passwords against known data breaches and warn you about weak or reused passwords.
2. Mozilla Firefox:
   • Type about:logins into the address bar and press Enter.
   • Click on the three dots (menu) in the top right corner, then select ‘Check Passwords’.
   • Firefox will scan your saved passwords against known data breaches and warn you about compromised or weak passwords.
3. Microsoft Edge:
   • Type edge://settings/passwords into the address bar and press Enter.
   • Click on ‘Check Passwords’.
   • Edge will scan your saved passwords against known data breaches and warn you about compromised or weak passwords.

Fixing Reused Passwords

1. Change Your Most Important Passwords First: Focus on accounts like email, banking, social media, and any other critical services.
2. Create Strong, Unique Passwords:
   • Aim for at least 12 characters. Longer is better!
   • Use a mix of uppercase letters, lowercase letters, numbers, and symbols (e.g., !@#$%^&*).
   • Avoid using personal information like birthdays or pet names.
3. Consider Using a Password Manager:
   • Password managers generate and store strong passwords for you, so you don’t have to remember them all. Popular options include LastPass, 1Password, Bitwarden, and KeePass (free).
   • Most password managers also offer browser extensions that automatically fill in your login details.
4. Enable Two-Factor Authentication (2FA):
   • 2FA adds an extra layer of security to your accounts by requiring a code from your phone or another device, even if someone knows your password.
   • Look for 2FA options in the security settings of each website you use. Common methods include authenticator apps (Google Authenticator, Authy) and SMS codes.
5. Regularly Review Your Passwords: Make it a habit to check your saved passwords periodically for any new breaches or weak entries.

Additional Tips

• Be wary of phishing attempts: Don’t click on suspicious links in emails or messages asking you to reset your password. Always go directly to the website itself.
• Keep your browser and operating system up-to-date: Updates often include security patches that protect against vulnerabilities.
