Hey there! @eveares
Can I add a second SmartThings account to my location/hub with all my devices, and then use that second SmartThings account to link to my Mums Amazon account?
You would need to create the Second Samsung Account first. Here’s a link to create a new Samsung Account that will be able to be added as a Member to your Hub’s Location: Samsung Account
Using the ST App, you would follow the steps in this troubleshooting article below to add the Samsung Account as a Member to the Hub’s location allowing you to link that Account with the desired Amazon Account via QR Code, Samsung Account Invite.
Note: You can only be signed into or switch between one Samsung Account on a device, This will allow direct access to the devices on the Smart Things Account if the new user has access to the ST App. (If the second user is able to create the account on their Android device, you have the option of hiding the app from app list or placing it into the secure folder as devices are able to be controlled and managed allowing for adding/deleting capabilities)

I hope this message finds you well!
