Wechat's public platform has been certified. Does Wechat's open platform need to be certified again?

I"d like to ask all the bosses.
the Wechat public platform I applied for has been certified, so whether the Wechat open platform needs to be certified again. Thank you.

Wechat public platform provides a service entrance for enterprises in Wechat's address book and enters the enterprise space, and provides three types of accounts: Subscription account, service number and Mini Program, with differentiated functions and independent accounts.
Wechat open platform provides applications for Wechat clients and becomes a third-party provider of applications. The application entry can be found in the discovery, in the official account, in Mini Program, in the mobile APP, or as a web page. Developers can use a unified Wechat account identity to achieve data across all kinds of Wechat accounts.
both should be independent and may need to be re-authenticated.
