It acts as your public account in the network and it can only be controled by the wallet owning it. Start by selecting Polygon ID in the network tab. If you haven't linked a DID to your account you'll be presented with the following screen.
Click on Create DID and a unique identifier will be generated automatically and associated to your address. You will be able so see it within your IDs tab.
To import a DID you must first import the wallet account to which it is associated. Click on Import DID and import the seed phrase of the wallet you want to add. The DID will automatically be imported and displayed within your IDs tab.
