Introduction
Email remains one of the most vulnerable communication channels. Almost all online services use your email for password recovery, identity confirmation, and communication. If an attacker gains access to your email, they can access many other accounts. This article covers key practices to protect your email.
Why Email Security Matters
Your email is a digital key to numerous important systems:
- Financial services and banking notifications
- Social networks and messaging apps
- Work tools and documents
- Personal photos and correspondence
- Data for recovering other accounts
One email compromise opens the door to everything else.
Setting a Strong Password
Your password is the first line of defense for your email.
Key Rules:
- Minimum 12 characters, preferably more
- Include uppercase, lowercase, numbers, and special symbols
- Avoid personal data (birthdates, names)
- Unique password for your email service

Two-Factor Authentication (2FA)
Two-factor authentication adds a second layer of protection even if your password is lost.
2FA Types by Security Level:

|---|---|---|
| Hardware Keys (YubiKey) | ⭐⭐⭐⭐⭐ | All important accounts |
| Apps (Google Authenticator) | ⭐⭐⭐⭐ | Email, banking services |
| SMS Codes | ⭐⭐ | Only as backup option |
| Email Notifications | ⭐ | Not recommended |
How to Enable 2FA:
- Go to your email service security settings
- Find the two-factor authentication section
- Choose your preferred verification method
- Save backup recovery codes
- Test the new settings work correctly
