Official Help for Implementing G Suite Two-Factor Authentication

The official help that was useful for implementing two-factor authentication in G Suite is as follows, for [administrators] and [internal users] respectively.

For Administrators

For Internal Users

G Suite Two-Factor Authentication Process Configuration Example

My configuration example when implementing the G Suite two-factor authentication process is as follows:

G Suite 2段階認証
  • Implementation: Only during introduction [Enable enforcement from specified date], after introduction [Enable enforcement now]
  • New user registration period: [1 week]
    ? With 1 day, there were many cases where the deadline had passed and individual support was needed, so I set it to 1 week. Ideally, I'd like to set it to 1 day.
  • Available two-factor authentication methods: [No restrictions]
  • Two-factor authentication policy grace period: [Allow registration of trusted devices in two-factor authentication process]

来月から、2段階認証を未設定だとログインできないようにして、セキュリティ向上させる予定です。 なにか質問があれば気軽に相談してください。 (From next month, we plan to prevent login without two-factor authentication setup to improve security. Please feel free to consult if you have any questions.)

That’s all about making two-factor authentication mandatory in G Suite from the Gemba.
