How to Set Secondary Admin for All OneDrive for Business Sites?

When a user creates SharePoint My Site or OneDrive for Business site collection, SharePoint assigns primary site collection administrator rights to the user. You may sometimes have to gain Admin access in situations such as a User leaving the organization, troubleshooting, etc.

In SharePoint on-premises environments, we have the “User Policy” option for web applications that provides Admin rights to the whole web application. In SharePoint Online, we don’t have user policies. Still, fortunately, we have the option to set secondary admin for all My sites to avoid adding them to every single site collection.
