POSTYPE uses a variety of technical measures and policy-based safeguards to protect your account information and personal data safely and to handle it in a lawful manner.
However, there are also some important guidelines you need to follow when using POSTYPE and in your daily life. If you follow the points below, you can prevent personal information from being leaked due to carelessness, and even if a risk of data exposure does occur, you can minimize the damage. This content was created with reference to guidelines on personal information protection from the Personal Information Portal.
1. Use a secure password that others can’t easily guess
A secure password is one that other people cannot easily guess or infer. The longer the password, the better, and the more complex the combination of uppercase and lowercase letters, special characters, and numbers, the harder it is to crack.
You should avoid passwords that follow a specific pattern (such as 'aaabbb', ‘qwerty’, etc.) or that contain personal information that others can easily find out (for example, your name, date of birth, mobile phone number, etc.).
Using different passwords for each service is also a good way to prevent password leaks. For example, you can take a commonly used password string and add the last letter of each service name in English (for POSTYPE, this would be 'e') to create a different password for each service.
2. Change your password regularly and use 2-step verification whenever possible
Changing your password frequently helps minimize both the possibility and the scope of personal information breaches. When you change your password, it is important not to reuse any of your previous passwords. If it is difficult to remember a new password each time, you can use commercial software or built‑in browser password managers that safely generate, store, and manage passwords.
In addition to passwords, using 2-step verification such as OTP is another way to strengthen your account security. POSTYPE provides 2-step verification using an OTP authentication app when logging in with email. For more details, please see How to enable/disable 2-step verification.
3. Do not share your personal information or account with others
Sharing your account with others is not only a violation of the terms of service for most services, but also greatly increases the risk of personal information being compromised. Be careful not to expose your account ID, password, and other information, and do not share them with people you know or with strangers.
In particular, POSTYPE continuously monitors and sanctions any activity involving the sale, purchase, rental, transfer, or sharing of accounts, and takes firm action against sellers, buyers, and renters alike. For more details, please see our Account Transaction Policy.
Including your personal information in posts, comments, messages, and other content, or encouraging others to share their personal information, also increases the risk of personal information breaches.
4. Be extra careful when using public computers or open environments
Security is inevitably weaker in environments where you have to use public computers, public Wi‑Fi, or devices in public places. Avoid entering highly sensitive personal information that could cause severe damage if leaked, such as your resident registration number or payment information, and pay more attention than usual to protecting your personal data and accounts.
After you finish using services on a public computer, always make sure you have logged out. Avoid logging in via linked social accounts such as Google or Naver. If you have no choice but to use social login, make sure you log out not only from the service you used but also from the linked social service itself.
When you are done, be sure to delete any personal data stored in the browser. Refer to the instructions for each browser and remove cookies and website data. (For example: Chrome, Microsoft Edge, Safari)
5. Do not download materials from unclear sources
Downloading links (URLs) or attachments from unclear sources via the internet, text messages, email, or messengers can lead to malware infection or personal information leaks. If you receive a link from an unknown source, do not click it; if you receive a file or email from an unknown source, delete it immediately.
One type of personal information crime that has recently been on the rise involves tricking users into downloading mobile apps through unverified links and then using malicious apps to steal personal information. Always install mobile apps through official app stores only. The POSTYPE app is also available exclusively from Google Play and the Apple App Store.
By following these guidelines—using secure passwords, changing your passwords regularly, using 2-step verification, avoiding account sharing, being cautious when using public places or public computers, and not downloading materials from unclear sources—you can use POSTYPE more safely. These simple steps will help strengthen the protection of your personal information and accounts, and allow you to enjoy your online activities more securely.
