It's possible to connect and use an External Wallet alongside or instead of the provided Passport Wallet in certain situations. If you'd prefer this, below are the steps necessary to get you set up. 

You have the option to either Import Items into Passport, or Link a wallet as view only.

Import Items into Passport: We want this option for this process

Step 1. Ensure that you're logged in to your Passport Account at passport.immutable.com 

Step 2. Using the navigation menu on the left, select the "External Wallets" page. On this page, click the "Link a MetaMask Wallet" option to start the process. A pop up should be shown, and allow you to choose between Importing Items to Passport, or more simply Linking a wallet as view only instead.  

Step 3. One selected, you'll be asked via a MetaMask pop up to sign a transaction. It's a good idea to check some of the information in here for accuracy. Starting with the pop up window originating from MetaMask, if linking a MetaMask wallet. Second, ensure the URL at the top matches the image below showing https://passport.immutable.com as the initiator. Finally, double check that the wallet address and Passport account email listed in the "Message:" section are correct. If it looks correct, you're ready to sign the transaction!

Step 4. Well done! You should now see your wallet successfully linked and visible under the "Linked Wallets" section. 

Congratulations! Your external wallet is now linked and you're ready to go.

You now have access to your any GOG NFTs that were in your External Wallet, and they will show up inside the in game Vault. From here you can move them into your active inventory and begin using your Guardians and other NFTs in game!
