I have used metamask on my old computer, where I had multiple accounts in it. When I moved to my new computer, I used the mnemonic phrase to import my existing wallet. The accounts that are now created out of the same seed phrases have different keys.
I know I could export the private keys on my old computer, and import the exact same account into the new metamask using the private key too, but I still do not understand why it is not the same automatically?
If I would have gotten my computer stolen, and I would have thought backing up only the seed phrases is enough, would I have lost all my balances?
