When I first installed Metamask and each time I start testrpc, I get a new mnemonic section of words to use for that testrpc.
I've already configured my MetaMask with four accounts from a prior run of testrpc, with that coinbase having ether that I mined on the testrpc.
So I wonder, if I put in a new set of mnemonic words from the new testrpc run, will I loose the existing accounts in Metamask and invalidate them? Can I go back to them by putting the original mnemonics later?
Or should I have started up testrpc the second time with the mnemonics from when I installed Metamask per this question:
