💡 In a nutshell

The recovery method depends on how you originally registered your if account.

Registration Method How to Reset
Email registration (メールアドレスで登録) Reset your password on the Password Reset Page
Google / X (formerly Twitter) / LINE registration Reset your password directly through each service’s own settings

🧭 Step-by-step Guide


① If you registered with your email address

  1. Go to the Password Reset Page

    👉 https://ifcf.jp/password/reset

  2. Enter your 「メールアドレス」 (email address) and submit

  3. You’ll receive a 「パスワード再設定メール」 – Password Reset Email

  4. Tap the link inside the email to set your new password

✉️ If you don’t receive the email, please check your spam folder or email filters.

💬 Once a new password is set, your old one becomes invalid.

Use the new password for all future logins.


② If you registered with Google / X / LINE

These login methods use OAuth authentication,

so you cannot reset your password directly on if.

Please reset it through the external service instead 👇
