If you are a user with Administrator role permissions you can control the access other people have to your Donorfy, to do this:

• Click on Users under Settings
  
  
• Select the ‘Existing Users’ tab

From this tab you can

• Change user access rights (permissions) - see this for more information
• Diable a user login - their user profile still exists they just can't login until you re-enable it (useful for long-term sickness or maternity/paternity, etc) - Notifications will still be sent from the system as the account is still present on your Donorfy. 
• Delete users - if you delete a user all of their inputs will remain against their name in Donorfy for auditing purposes.
• Disable Two-Factor Authentication for a user
