Keystroke logging is a method used for monitoring and recording keystrokes on a keyboard. To prevent keystroke logging, a few steps should be taken:

1. Use a physical security token, such as a USB key, password generator, or biometric authentication to access sensitive sites and applications
2. Check for updated versions of software that may include keystroke logging prevention
3. Enable two-factor authentication for all online access
4. Set strong passwords for logins and encrypt sensitive data
5. Be aware of malicious links and websites that can contain key logging features
6. Keep your anti-virus and firewall software up to date
7. Clean up your computer regularly with a trusted anti-malware application
