We change the authentication method of business portal from 1-step verification to 2-step verification to enhance security.
(Please see here in detail. )
After login from [Log in with 1-step verification (old authentication method)] below, click [Initial setting for 2-step verification]button at the top of dashboard page to set up this.
We ask that you set up 2-step verification by April 24th. The old authentication method will not be available after that.
We apologize for any inconvenience, thank you for your understanding and cooperation.
