Since this tutorial is focused around Metamask, I don't think we need to reference other ways. May cause confusion.
Suggested change
| var password = web3.eth.getStorageAt(instance, index);` |
| ``` | ||
| var password = web3.eth.getStorageAt(instance, index);` | ||
| // For Metamask use callback function | ||
| web3.eth.getStorageAt(instance.address, 1, (err,res)=>{password=res}); |

This may be an easier example.
Suggested change
| web3.eth.getStorageAt(instance.address, 1, (err,res)=>{password=res}); | |
| web3.eth.getStorageAt(contract.address, 1, function(error, result) {password = web3.toAscii(result)}) |
| We'll be able to finally see the key string to unlock the vault! | ||
