I’ve read a few guides on how people were able to use dev tools in their browser to download their blockchain wallet file in the past,
Yes, but that was in the past and it's uncertain if it'll work today even if your wallet is old.
It wont work in newer wallets.
It requires your WalletID and the step is simple; type their URL with your walletID like this:
blockchain.info/wallet/<WalletID>?format=jsonFor example:
blockchain.info/wallet/aaaaaaaa-aaaa-aaaa-aaaa-aaaaaaaaaaaa?format=jsonDoes anyone know a way I can download a copy of my password protected wallet to I have access it locally?
The old BTCRecover's extract script didn't work in my test which I remember working in the paste few years.
Here's the script if you're interested bu as I've mentioned, it failed with "
HTTP Error 403" in my test.
