In today's digital world, site (cmh.or.kr) relying on external platforms is now essential for daily operations. From online file sharing and social network connections, these tools optimize productivity and simplify tasks. However, with convenience comes responsibility—especially when it comes to managing account security. Relying on external platforms means allowing them to handle your personal details, and that trust must be consistently evaluated to reduce risks.

One of the first steps in securing your accounts when using third-party services is to determine the scope of information being accessed. Before connecting your account to a new app or service, review the permissions it's requesting. Does a fitness tracker really need access to your calendar or contacts? If the answer is no, consider whether the service is worth the risk. Limiting access to only the data necessary lowers the chance of unauthorized access.

Use strong, unique passwords for each service you use. Avoid copying login credentials between sites, despite convenience. If one service is compromised, a reused password could give attackers access to multiple accounts. Consider relying on a trusted password vault to handle secure credential storage. This way, you avoid the pitfalls of weak or repeated passwords, and you’re less likely to make mistakes.

Activate second-factor login methods on every available service. This adds an extra layer of security by demanding an additional identity check—such as a code from your phone or a biometric scan. Even if your password is stolen, they’d still lack the required second piece to gain entry. Look for services that offer app-based verification over SMS-based options, as text-based verification is susceptible to interception.

Frequently audit the external tools connected to your digital profiles. Most major platforms, like Microsoft, Google, and Facebook, allow you to view and revoke access to third-party integrations. Remove access to any service you no longer use or trust. This simple step shrinks potential entry points and helps ensure that only trusted services maintain access.

Keep up with the latest security alerts and incident reports. If a service you use suffers a security incident, respond immediately. Change your passwords, enable 2FA if you haven’t already, and monitor your accounts for suspicious activity. Many services send real-time warnings about suspicious access attempts—make sure you’re subscribed to these security updates.

Finally, maintain strong online habits. Avoid opening unknown attachments or strange URLs. Phishing attacks frequently replicate official interfaces to trick users. Always verify the sender and double-check URLs before entering any information.

By being proactive and mindful about your interaction with external platforms, you can enjoy their benefits while significantly reducing the risks. Security isn’t a one-time task—it’s an lifelong commitment. With a few consistent habits, you can protect your accounts and maintain control over your digital identity.
