The WTO is looking to eliminate the old email address, as the agency prepares to launch a new digital identity service.
The agency will use an encrypted, two-factor authentication system, which it hopes will prevent fraud.
WTO President David Noyes said in a statement that the transition will be seamless and free for all, and that the new service will be available in 2017.
The WMO said in January that it planned to launch an online platform by 2018.
The change is an attempt to streamline and simplify the WTO’s website.
The agency also wants to increase transparency in its workforce.
The announcement comes as the WMO continues to face criticism for its treatment of women.
In March, the WO’s deputy chief executive, Kate Allen, resigned after she was found guilty of sexual harassment.WTO officials have also been accused of sexism, with a report by the U.S. Department of Labor alleging that the agency discriminated against female employees in hiring and promotion.
