Warning: Exporting your account could be risky as it displays your private key in clear text. Therefore, you should make sure no one else sees, or otherwise is able to capture a screenshot while you retrieve your private key, to avoid possible loss of your Ether/tokens. Many phishing campaigns would ask for your private key, which would help them gain access to your accounts. You should never share your private key with anyone, including MetaMask team. We will not ask for your private key when we manage, or troubleshoot your issues.
