Essentially, what the question means is whether we can undergo the MetaMask sign in process on multiple devices or not. The answer to this is yes, you can definitely do that. However, this should be very clear that you cannot do the MetaMask sign in into two devices at a time and the reason behind this is a feature called “origin”.
There will be a separate virtual knot between the wallet and each device and this is the reason why there will be different passwords for undergoing MetaMask sign in process on different devices. And, you will also need to add any of your RPC networks or tokens to each of the devices. In case you have imported your wallet to a new device and it does not appear in it, you will need to click on the circle icon available on the top right corner of the screen and choose the option named “Create account”. And all your existing accounts associated with the wallet will show up immediately.
