How can I let my users install apps?

Hello marte241,

Thank you for using Apple Support Communities.

We understand that you would like to allow users to install apps they want. To be able to purchase and install apps, they will need access to the App Store and for that they will need to be a member of a Family Sharing group or have access to your Apple ID and password. You can take a look at these articles for more information about setting up and using Family Sharing:

Best regards.

Yes, you can have Managed Apple IDs to allow users to access services such as iCloud and the App Store. To download and install Apps they may need to link the Managed Apple ID to their own.
