Basing on creating a new wallet 1, I create another new wallet 2. But I can’t gain private key for wallet 2 like I do in metamask. I when I use memomic phrase to recover my wallet, I can only recover wallet 1 but I can’t recover wallet 2. Wallet 2 is permanently lost.
I guess this is because all new accounts in Fuel Wallet are derived from the same mnemonic phrase, so the phrase won’t be different for your wallet1 and wallet2. If you import this seed phrase, you’ll get wallet1. After that, if you create a new wallet, you’ll get the same wallet2.
This feature to export private keys was released on version 0.7.2 of the wallet. You can download this version now. https://wallet.fuel.network
