Want to Deactivate Administrator User

Want to deactivate Administrator User

We need to verify 2 things:

1. We aren't logged in as the user that we are trying to deactivate.

2.  At least there is one more system administrator user in your org

We can't deactivate our self.

We can create only 2 users with System Administrator profile in developer org.

While creating a user we need to make sure that we have changed user license to Salesforce. 

Select Profile as System Administrator and provide all required details and save the User. 

Once we have saved the user then we need to click on edit and deactivate this user.
