Resolving Access Challenges for Your Sundai Account

⚠️ I've forgotten my password.

Cause: You cannot recall the password associated with your 駿台マイページ account.

Solution: We know being locked out is stressful. The fastest fix is to use the パスワードをお忘れの方 (Forgot your password?) link conveniently located on the login page. Follow the prompts to reset your password using your registered email address.

⚠️ I can't remember my login ID (email address).

Cause: You have forgotten the email address used as your login ID for your 駿台マイページ.

Solution: Click on the ログインIDをお忘れの方 (Forgot your login ID?) link on the login screen. Your login ID is typically the email address you used when you first registered with Sundai.

⚠️ My account seems to be locked, or I can't log in after multiple attempts.

Cause: Repeated incorrect login attempts might temporarily lock your account for security reasons, or there might be a system maintenance period.

Solution: First, check for any stated maintenance hours, such as those noted for the web application site (Monday-Saturday 21:00-5:00, Sunday/Holidays 18:00-5:00 JST). If it's outside these hours, wait a short period and try again, ensuring your credentials are correct. If the issue persists, contact Sundai support for assistance.

⚠️ I am a new user and cannot log in.

Cause: New registrations sometimes require a short processing time, or you might be using a temporary password for the first time.

Solution: If you are a first-time user and received a temporary password via email, ensure you are entering it correctly. Some systems require a password change upon first login. Also, be aware that registration might not be immediately active; for instance, the web application site mentions waiting until 5:00 AM if you registered just before that time.
