Lesson 5 : Question About MetaMask Security

[wilonweb]

Hello
Just to be sure, before putting my private key on Alchemy with a testNet

I have a MetaMask (a chrome extension) where I have to put my "main" password to access the application
When it is open we have several networks (rinkeby, mainet....)
When a network is selected, I have a profile with multiple Public Key Accounts ( Account 1, Account 2, .... )

So if on my BNB smartChain mainnet, I have a real account with real money.

Can I still select a Rinkeby network account and extract my private key to do an alchemy test?

Thanks

Hey, NinjaTurtles-cloud

You should read this thread.

The safest option: use a separate MetaMask wallet for testing.

But if you create a separate account through the «Create Account» button specifically for testing purposes, and then export the private key of this particular test account, it does not reveal the data of other accounts with real funds. The mnemonic phrase in this case should never be disclosed, because in this case there will be access to all the created accounts in the MetaMask.

upd. If you select account 1 in two different networks, its private key will be the same. Changing the network does not affect the private key.

Do you know how I can have a separate Metamask account?

I tried to create a separate wallet, but couldn't get a new one.
I only have (remove metaMask from googlechrome) and if I use Brave browser or a second google chrome account it's the same

Make a new profile in your brave browser, call it "development" or something - and add a new metamask to that one
