Dear Colleagues,

I am writing this notice to inform you about the OTP authentication guide.

In addition to the existing email authentication method used during login, we have now introduced OTP authentication as a new option.

Although OTP authentication is not mandatory, it has been added to enhance both convenience and security.

Please refer to the guide in each language to set up OTP authentication:

• OTP Authentication Guide (Korean)

• OTP Authentication Guide (English)

• OTP Authentication Guide (Spanish)

Thank you for your attention.
