Online Privacy and Security: A Comprehensive Guide to Protecting Your Data
Online security and privacy have become major concerns in the digital age. With the explosion in cyber attacks and data breaches, it’s imperative to take steps to protect your personal information. This guide offers practical and effective advice on how to strengthen your online security.
1. Activate Multi-Factor Authentication (MFA) – Online Security and Privacy
Multi-factor authentication (MFA) adds an extra layer of security by requiring a second proof of identity. It is essential for protecting sensitive accounts such as e-mail, banking and social networking.
MFA methods :
- SMS codes: A code sent to your phone. Although convenient, this method is vulnerable to SIM swap attacks.
- Authentication applications: Use applications such as Google Authenticator or Authy to generate offline codes.
- Biometrics: Fingerprint or facial recognition to secure your devices.
Tip: Prioritize MFA activation on your most sensitive accounts.
2. Use strong and unique passwords – Online Security and Privacy
A strong password is your first line of defense against intruders.
Characteristics of a good password :
- At least 12 characters.
- A combination of upper and lower case letters, numbers and symbols.
- No common words or personal information.
Tip: Create a complex phrase like “MyC0deEstS#curisé!23” to make it memorable and hard to guess.
3. Setting up a Password Manager – Online Security and Privacy
Password managers simplify the management of your credentials while increasing their security.
Advantages :
- Generate long, random passwords.
- Secure storage in an encrypted safe.
- Easy access with a single, strong master password.
Recommendations: Explore tools such as LastPass, Dashlane, or Bitwarden.
4. Verify and Update Recovery Information – Online Security and Privacy
Your recovery information is used to restore access to your accounts in the event of a problem.
Please check:
- Emergency email: Secure it with MFA.
- Telephone number: Make sure it’s up to date.
Caution: Avoid using vulnerable e-mails or numbers.
5. Check Connection Activity and Unknown Devices – Online Privacy and Security
Most online services offer activity logs.
Actions to be taken :
- View connection history.
- Delete any unrecognized devices or sessions.

6. Revoking Access to Third-Party Applications – Online Privacy and Security
Some third-party applications can compromise your accounts.
Steps :
- Go to Settings > Security > Connected applications.
- Revoke access to unused or suspect applications.
Impact: Reduce the risk of vulnerabilities being exploited by third parties.
7. Setting up Account Notifications – Online Security and Privacy
Security alerts let you react quickly to suspicious activity.
Activate notifications for :
- Password changes.

Where: These options are available in the security settings of your online accounts.
8. Update Security Issues – Online Security and Privacy
Security questions can be a loophole if they’re easy to guess.
Best practices :
- Replace obvious answers with fictional, memorable ones.
Example: Favourite city: Pizza123.
9. Backup Critical Data Regularly – Online Security and Privacy
Backups protect your information against ransomware and accidental loss.
Backup options :
- Encrypted external hard drives.
- Secure cloud services: Activate MFA for extra protection.
