Resolving Musubi Account Access Challenges

⚠️ Account Not Recognized During Login

Cause: Your email address might not be registered, or there might be a typo.

Solution: If you receive a message indicating your email address is not registered, you will need to proceed with new member registration to create your Musubi.net account.

⚠️ Incorrect Password or Login Issues

Cause: Typographical errors, incorrect character input (e.g., full-width vs. half-width), or a forgotten password.

Solution: First, verify that your Caps Lock or Num Lock keys are not accidentally active. Ensure you are inputting your password using half-width alphanumeric characters. If you've forgotten your password, utilize the "Forgot Password?" link on the login page to initiate a reset process, which typically involves receiving an authentication code via email.

⚠️ Not Receiving Authentication Codes or Other Musubi Emails

Cause: Emails being blocked by spam filters or incorrect email address on file.

Solution: Check your spam or junk mail folders first. To ensure reliable delivery, add [email protected] to your safe sender list. If you continue to experience email delivery problems or cannot access your registered email, contact the Musubi service counter for further assistance.
