Two-factor authentication (2FA) is an additional layer of security that helps protect your accounts from unauthorized access. By receiving a verification code via text message or email, 2FA greatly reduces the chance of someone successfully breaking into your accounts, even if they have your username and password. To effectively use 2FA for your accounts, consider the following tips:

1. Enable two-factor authentication: Wherever it is available, switch it on and bind it to your mobile phone.


2. Protect your authentication method: Be careful with who you share your code with, and do not fall for phishing attacks.


3. Manage your passwords: Make sure your passwords are strong, unique to each account, and that you change them regularly.


4. Manage your accounts: Regularly review and shut down any accounts you no longer use.


5. Ensure backups: Regularly back up your data in a secure external drive or cloud service.
