This section outlines the steps for implementing multi-factor authentication in Email. In addition to authentication by user ID and password, authentication by one-time password can be obtained after setting up Multi-Factor Authentication (MFA). Having two or more authentication factors enhances your cyber security with email.
In the email system offered by CIS, multi-factor authentication, which incorporates OTP in addition to ID and password verification, is available when accessed from a non-global IP address.
An OTP is a single-use password with a limited validity period. The email system can generate OTPs in two ways, so please choose the method that best suits your situation. | 情報 |
|---|
| - Generate an OTP by installing a dedicated app on your smartphone.
- Receive one at a private email address (an email address other than @kit.ac.jp or @edu.kit.ac.jp).
|
However, if circumstances arise, such as changing or losing your smartphone model or forgetting the password for your private email address, please configure the system to ensure you have both options available.
Followed by the setup of the dedicated app, proceed to set up your private email address in this process.
| 注意 |
|---|
| Multi-factor authentication is applied when the setting is enabled for wireless LANs with authentication (KITnetX, KITnetW), information outlets with authentication, and eduroam. However, for the global IP address connections, such as seminar rooms, self-study rooms, web browsing corners, web browsing rooms, faculty rooms, student rooms, etc., multi-factor authentication is bypassed, even if the setting is enabled. |
