# Transferring Polkadot-JS Apps Accounts/Addresses From One Computer to Another

Note: This will overwrite any existing accounts with the same pubkey on your new computer. This generally should not make a difference (since it can still access the same account), but might if you have e.g. an account which was stored externally in the extension on the old computer but was created directly in browser on the new one.

This has been tested on Brave and Chrome, but not other browsers.

1. Go to Polkadot-JS Apps
2. Go to JavaScript console (on Brave, NOT on Polkadot-JS)
3. Type in the command `JSON.stringify(localStorage)`
4. Copy and paste the returned string to a text editor.
5. Check that the string you pasted both begins and ends with a tick mark (`'`). If not, add one to the beginning and end.
6. Save and send that JSON file to the new computer.
7. On new computer, go to Polkadot-JS Apps
8. Open the Javascript console
9. Set a variable `raw` equal to the JSON you created =

raw = ... copy-pasted json from original computer ...

10. Run the following code:

accounts = JSON.parse(raw);
for (var key in accounts) {
    if (accounts.hasOwnProperty(key)) {
        val = JSON.stringify(accounts[key]).replace(/\\/g,'').slice(1,-1);
        console.log(key + " -> " + val);
        localStorage.setItem(key, val);
    }
}

11. Refresh Polkadot-JS App browser and check Accounts and Addresses pages. All of your accounts and addresses should now be available.
