Hi,

We have some limitations on our managed MongoDB cluster. For your reference, You can follow the below document on MongoDB limitations :

https://docs.digitalocean.com/products/databases/mongodb/#mongodb-limits

​​​​​​You cannot add users or edit permissions using the mongo shell for MongoDB managed database. Users must be added to the cluster using the DigitalOcean Control Panel.

And new users will receive the permissions of the doadmin user by default. You can’t change these permissions at this time; Our team is aware of this limitation and working on a workaround.

Adding to this only time we send the password over the wire is during our create a response and during our reset password response; we don’t store or manage the users’ password.

https://docs.digitalocean.com/products/databases/mongodb/how-to/manage-users-and-databases/

As we continue to work on improving our products and services, we encourage you to share your thoughts, ideas, or feedback you have at https://ideas.digitalocean.com/

I hope this helps!

Regards,
Rajkishore
