How to Create an Account

Last Updated: April 2026

Getting Started with CORE

The submission and management of articles are conducted through the ETFLIN Centralized Oversight and Review Ecosystem (CORE). To access the system, you must first create an account using your full name, email address, and a secure password.

Account Creation and Login

To begin, navigate to the Login Page at https://etflin.com/login or click the Sign In button located in the top-right corner of the navigation bar (Figure 1). If you do not yet have an account, on the Login Page, click the Create One button (Figure 2) to proceed to the Registration Page.

The password must be at least 8 characters long. It is recommended to use a combination of lowercase letters, uppercase letters, numbers, and symbols to make your password more secure.

Complete all required fields on the registration form and click Create Account. The system will validate your information and display a notification in the top-right corner of the screen. A successful registration is indicated by a green notification with Code 200 (Figure 3). A red notification indicates that an error has occurred during the process.

Email Verification

After submitting the registration form, check your email inbox for a verification message from ETFLIN. If you cannot find it, check your Spam or Junk folder. The email would look like as shown in Figure 4.

Open the email and click the Verify button to activate your account. Alternatively, copy and paste the complete verification link into your browser. Do not remove or modify any part of the link, including the six-digit verification code at the end.

Once verification is successful, a green notification displaying “Verification Success” will appear. Your account is now active. Return to the Login Page and sign in using your registered email address and password.

Troubleshooting Common Errors

Password Mismatch. This error occurs when the password and confirmation password do not match. Check both fields and enter the same password in each.

Email Already Registered but Not Verified. If the email address is already registered but has not been verified, the system will send another verification email automatically. Check your inbox and Spam or Junk folder, then follow the verification instructions above.

Verification Email Not Received. First, check that you entered your email address correctly and review your Spam or Junk folder. If you previously entered an incorrect email address, register again using the correct address. If your address is already registered but remains unverified, follow the instructions for pending verification rather than creating another account with a different address.

If you have checked these items and still cannot receive the verification email, contact ETFLIN at halo@etflin.com for assistance.
