I personally use Yubico keys for my own data and enjoy them quite a bit. However, that doesn't work for you there is a second option to secure your online data and that is to set up MFA. MFA is not as secure, as it can still be hacked using social engineering.
MFA
MFA, short for Multi-Factor Authentication, is a security mechanism that requires users to provide multiple pieces of evidence to verify their identity when accessing a system, application, or service. It adds an extra layer of protection beyond the traditional username and password combination by introducing additional factors that are harder to compromise.
The primary goal of MFA is to prevent unauthorized access, data breaches, and identity theft by ensuring that the person attempting to log in or access sensitive information is indeed the legitimate user. It achieves this by combining at least two or more of the following authentication factors:
Knowledge factor: This is something the user knows, such as a password, PIN, or answers to security questions. It is the most common and basic form of authentication.
Possession factor: This is something the user possesses, like a hardware token, a physical key, or a mobile device that receives a one-time password (OTP) via SMS or a dedicated authentication app.
Inherence factor: This is something inherent to the user, typically related to their physical characteristics or behavior. Examples include fingerprints, facial recognition, voice patterns, or iris scans.
By requiring multiple factors, MFA significantly strengthens the security of the authentication process. Even if an attacker manages to obtain or guess the user's password, they would still need access to the additional authentication factors to gain entry. This makes it much more challenging for hackers to impersonate legitimate users and gain unauthorized access.
MFA has become increasingly popular and widely adopted across various industries and applications. It is commonly used in online banking, email services, cloud platforms, social media, and corporate networks, among others. The adoption of MFA is driven by the need to combat evolving cybersecurity threats and protect sensitive information from unauthorized access.
The benefits of MFA are numerous:
Enhanced security: MFA significantly reduces the risk of unauthorized access and data breaches, as attackers would need to bypass multiple authentication factors.
Improved user authentication: By using multiple factors, MFA provides a higher level of confidence in verifying the identity of users, making it more difficult for attackers to impersonate legitimate users.
Flexibility: MFA can be implemented using various combinations of authentication factors, allowing organizations to choose the most suitable approach based on their requirements and user preferences.
Compliance requirements: MFA is often a mandatory security measure to comply with industry regulations and data protection standards.
User awareness and accountability: MFA promotes user awareness about security and accountability for their own credentials, as they become an integral part of the authentication process.
It is important to note that while MFA significantly improves security, it is not foolproof. Some factors, such as SMS-based OTPs, may still be vulnerable to attacks like SIM swapping or phishing. However, newer forms of MFA, such as biometrics and hardware tokens, provide stronger protection.
Overall, the adoption of MFA is a crucial step in mitigating the risks associated with unauthorized access and data breaches, and it is recommended for individuals and organizations seeking to enhance their security posture.

Identifying Social Engineering
What is Soical Engineeing?
Social engineering is a deceptive manipulation technique used by malicious actors to exploit human psychology and manipulate individuals into performing actions or divulging sensitive information. It leverages the trust, helpfulness, curiosity, or fear of people to bypass security measures and gain unauthorized access to systems, networks, or confidential data.
How to Identify Social Engineering
Social engineering techniques can take various forms, including:
Phishing: Attackers send deceptive emails, messages, or phone calls impersonating legitimate entities, such as banks or service providers. They trick individuals into revealing sensitive information like passwords, credit card details, or account credentials.
Pretexting: Attackers create a false scenario or persona to gain someone's trust. They may pose as a colleague, IT technician, or authority figure and use social interactions to extract confidential information or manipulate victims into performing specific actions.
Baiting: Attackers offer something enticing or appealing to individuals in exchange for sensitive information. It could be a free gift, a fake job opportunity, or a USB drive infected with malware. The aim is to entice victims into taking actions that compromise their security.
Tailgating: This technique involves an attacker following a legitimate person into a restricted area without proper authorization. By exploiting a person's politeness or lack of awareness, the attacker gains physical access to a secure location.
Social engineering can have severe consequences, including unauthorized access to systems, identity theft, financial loss, and damage to an individual's or organization's reputation. To protect yourself from social engineering attacks, here are some tips:
Be vigilant and skeptical: Exercise caution when receiving unsolicited emails, messages, or phone calls. Verify the identity and legitimacy of the person or organization before sharing sensitive information or performing requested actions.
Verify requests independently: If someone asks for personal information or instructs you to perform an action, independently verify their request through a trusted source. Use official contact information, not information provided in the suspicious communication.
Be cautious with email attachments and links: Avoid clicking on suspicious links or downloading attachments from unknown sources, as they may contain malware or lead to phishing websites. Hover over links to check their destination before clicking.
Practice strong password hygiene: Use unique, complex passwords for each online account, and consider using a password manager. Enable multifactor authentication (MFA) whenever possible to add an extra layer of security.
