Hi,
where can I find my private key in Metamask?
I have only the seed, at the moment.
You can export the private keys in metamask,just click the three dots at the rightside of the wallet's name and you will find the export option,along with scan with etherscan,and qr code.This is the best security you will have in your browsers and ive been using this for about a year and without any problems.It is a protection for the phishing sites,and it will give you a peace of mind in every transactions you made because your keys will be stored in metamask.
