Essential tips and strategies to protect your email accounts and communications from threats.

Introduction

Email remains one of the primary attack vectors for cybercriminals. In 2025, with increasingly sophisticated phishing attacks and social engineering, protecting your email is more important than ever.

Strong Authentication

Use Strong, Unique Passwords

•Minimum 16 characters with mixed case, numbers, and symbols

•Never reuse passwords across services

•Use a password manager to generate and store passwords

Enable Multi-Factor Authentication (MFA)

MFA adds a second layer of security beyond passwords:

Method	Security Level
Hardware keys (YubiKey)	Highest
Authenticator apps	High
SMS codes	Medium

Consider Passkeys

Passkeys are the future of authentication—phishing-resistant and more convenient than passwords. Major email providers now support them.

Recognizing Phishing Attacks

Red Flags to Watch For

1**Urgency**: "Your account will be suspended immediately"

2**Generic greetings**: "Dear Customer" instead of your name

3**Suspicious links**: Hover over links to see actual URLs

4**Mismatched sender**: Display name vs. actual email address

5**Unexpected attachments**: Especially .exe, .zip, or macro-enabled documents

Managing Email Privacy

Use Temporary Email Addresses

For signups and one-time verifications, use services like Tempo to:

•Protect your real email from spam

•Avoid marketing lists

•Maintain privacy when testing services

Separate Email Accounts

•Primary: Important personal and financial communications

•Secondary: Shopping, newsletters, social media

•Professional: Work-related communications only

Conclusion

Email security requires constant vigilance and multiple layers of protection. By implementing these best practices, you can significantly reduce your risk of email-based attacks.
