Understanding Digital Hygiene
Digital hygiene refers to security practices and habits that protect your online accounts, devices, and personal information. Just as physical hygiene prevents disease, digital hygiene prevents compromise. Most cyber attacks succeed not through sophisticated hacking but through exploiting poor digital hygiene habits.
Daily Digital Hygiene Practices
Morning Routine
- Check email for suspicious messages before clicking links
- Review recent activity on important accounts (email, banking, social media)
- Verify no unauthorized logins occurred overnight
- Ensure antivirus is up-to-date and running
- Confirm VPN is active if using public networks
Email Management
- Delete suspicious or unsolicited emails without opening attachments
- Avoid replying to phishing emails
- Report spam and phishing to your provider
- Review forwarding rules monthly for unauthorized changes
- Check connected apps with email access
- Verify sender addresses carefully before clicking links
Password and Authentication Practices
- Never enter passwords on unsecured networks
- Use unique, complex passwords for important accounts
- Enable multi-factor authentication wherever offered
- Verify two-factor codes come from expected sources
- Change passwords immediately if you suspect compromise
- Regularly review connected apps and revoke unused access

Building and Maintaining Habits
- Start small with 3–4 critical habits and build consistency
