- Reusing passwords is the biggest risk, and a password manager fixes it.
- Protect your email and bank first, then everything else.
- Use an authenticator app instead of text messages where you can, and save your backup codes.
The Short Answer
Most account break-ins happen because one password was reused or stolen, then tried on other sites. A password manager removes that risk by creating and remembering a different strong password for every account. Add two-factor authentication to your most important accounts, and you block most everyday attacks. You can finish the basics in an afternoon.
Why Reused Passwords Are the Real Danger
When a website is hacked, criminals test the leaked email and password on banks, email and social media. If you used the same password everywhere, one leak opens many doors. A password manager lets you use a long, random password on each account without memorising any of them.
Choose a Password Manager
Pick a well-known provider with a clear security record, independent audits where available, apps for your phone and laptop, and a way to recover your account. Our comparison of 1Password and Bitwarden is a good place to start. Prices and features change, so check the provider's own website before you pay.
Set It Up in Five Steps
1. Create a strong master password. Use a long phrase of four or more unrelated words that you have never used anywhere else. This is the only password you must remember.
2. Install it everywhere. Add the app and browser extension on your phone and computer.
3. Protect the big accounts first. Change the passwords for your email, bank, mobile money and social media, because email can reset all the others.
4. Import and clean up. Move saved browser passwords into the manager, then delete them from the browser.
5. Replace weak and repeated passwords over the next few weeks, starting with the accounts that hold money or personal data.
Add Two-Factor Authentication
Two-factor authentication (2FA) asks for a second proof after your password. Use the strongest option each account offers:
| Method | Strength | Note |
|---|---|---|
| Security key | Very strong | Best for email and finance, but you must keep a spare |
| Authenticator app | Strong | Works without network and is safer than SMS |
| SMS code | Basic | Better than nothing, but open to SIM swap attacks |

Plan for Getting Locked Out
Save the backup codes each service gives you and store them in your password manager or print them and keep them somewhere safe. Write down your master password recovery option. Tell one trusted person where to find emergency access, if your manager supports it.
