Authentication in Cyberattack Prevention

Entering a new year is the ideal time to recall and reflect on our cybersecurity practices. A crucial theme in the cybersecurity ecosystem is authentication, and as technology advances, it is important to be aware of best practices in this area and how to leverage this tool.

Authentication is the process that verifies a user's identity, ensuring that the person accessing a particular system or device is truly who they claim to be. Authentication can be done through passwords, biometrics, or two-factor authentication, with the latter being a measure to consider regarding defense against cyber threats. Here are 5 essential tips to keep your accounts secure:

1. Use Strong Passwords

Utilize unique and strong passwords, composed of a combination of letters, numbers, and symbols as the first step towards more secure access. Avoid obvious passwords, and do not use the same password for different accounts. If one account is compromised, others with the same password are at risk of an attack.

2. Multi-Factor Authentication

Multi-factor authentication is a tool that should be used in accessing systems and devices for its additional layer of security. This extra security layer requires not only the password but also a second element, such as a code sent via text message or a fingerprint. This way, you can prevent unauthorized access and protect your personal and professional information.

3. Regular Password Updates

It's important to change your passwords regularly, for example, the Wi-Fi passwords of the accesses you use while teleworking, as this makes it less likely that third parties will be able to access your systems and devices.

4. Monitor Suspicious Activities

Pay attention to unusual activities in your accounts. Rapid detection of suspicious activities through notifications or questionable messages can prevent potential harm. If you receive suspicious notifications or notice unauthorized access, it is essential to take immediate action to ensure the security of your data.

5. Use Biometrics

When possible, consider using biometric authentication methods, such as fingerprint or facial recognition. These methods are more challenging for cyber attackers to replicate.

6. Periodically check permissions

When access permissions are requested, you must ensure that they are the most appropriate and necessary for the functionality of each application on the device. This protects against possible attacks, preserves the privacy of data and systems, and reduces exposure to cyber threats.


Investing in robust authentication is not just a precaution but a way to safeguard against increasingly sophisticated cyberattacks. It is crucial to know how to protect your online accounts and adopt best practices in cybersecurity. By embracing these practices, you will be one step ahead of cyber attackers and strengthen defenses against identity theft, unauthorized access, and other types of threats that can compromise your privacy and online security.
