I use truffle develop. It seems to me that the accounts in truffle develop are persistent. Pleas correct me if I'm wrong. How can I import the accounts from truffle develop into MetaMask?

With release V4.0.x of the Truffle framework, whenever you start Truffle using truffle develop it starts a new local in-memory Ethereum private network using the same 12 word mnemonic:

It is, therefore, possible to import the accounts into MetaMask by following the following simple steps.

When you open MetaMask in your browser, there is an option to "restore from seed phrase":

Enter the truffle develop phrase and then click on okay:

Press the "create account" up to 10 times (as many as you want access to) - it will generate the same addresses as seen in the truffle develop console (it's a deterministic process):

restore the accounts
