How to Log In to Your Konami ID Account on Mobile (Yu-Gi-Oh! Master Duel)

Note: There’s no need to delete game data when logging into a new account.

Step 1: On the game’s title screen, tap DATA TRANSFER.

⚠️ Do not tap DATA TRANSFER from the main lobby or in-game menu (three-line icon). Doing so may cause login issues. We are not responsible for improper transfers.

Step 2: Select Data Link via KONAMI ID.

Step 3: Enter the username and password you received when purchasing.

If entered correctly, the next screen will confirm the login.

Step 4: Return to the game. If a confirmation message appears, everything is set—you can now play!

Extra Tip: If you follow all steps correctly but still receive an error at login while on Wi-Fi, switch to 4G and try again. This fixes the issue in some cases. You can return to Wi-Fi after logging in.
