2026年6月5日を更新しました

2 要素認証 (2FA) は、パスワードが漏洩した場合でも、Discord アカウントを保護します。 iPhone、iPad、または Mac で Authenticator App を使用して Discord 検証コードを生成するには、以下の手順に従ってください。

Download Authenticator App
Download Authenticator App from the App Store on your iPhone, iPad or Mac. It's free and no sign-up is required.
Open Discord settings
Click the gear icon next to your username to open “User Settings” → “My Account”.
Enable authenticator app
Click “Enable Authenticator App”, confirm your password, and Discord will show a QR code and setup key.
Scan the QR code with Authenticator App
Open Authenticator App, tap the + button and scan the QR code shown by Discord. If you can't scan it, choose the manual option on Discord and type the setup key into the app instead.
Enter the 6-digit verification code
Type the 6-digit code from Authenticator App back into Discord to confirm the setup. The code refreshes every 30 seconds.
Save your backup codes
If Discord offers backup or recovery codes, download or write them down and store them somewhere safe. They let you regain access if you ever lose your device.
