Now Metamask will show you your Wallet Seed (secret phrase). This is your actual wallet passcode. This seed is even more critical than the Metamask password. With this seed anybody, anywhere, could access your crypto wallet, even if they cannot access your Metamask. So make sure you store it safely in a non-digital medium (piece of paper inside a safe, a hard-drive disconnected from the Internet or on a Hardware Ledger). This is the last line of defence for your crypto assets. If your Wallet Seed is stolen, you cannot do anything to recover the assets.
