Describe your question in detail.

In my own sdk I use the following to access Aptos account through private key:

const aptosAccount = Account.fromPrivateKey({
  privateKey: ...
})

How can i do the same browser side? window.aptos.account and window.aptos.getAccount() both return account info. I need account of Account that I can pass to this:

const senderAuthenticator = aptos.transaction.sign({
  signer: account // <-- this
})

What error, if any, are you getting?

No response

What have you tried or looked at? Or how can we reproduce the error?

window.aptos.account and window.aptos.getAccount() both return account info. I need access to Account which I can use to pass to aptos.transaction.sign

Which operating system are you using?

macOS

Which SDK or tool are you using? (if any)

N/A

Describe your environment or tooling in detail

I'm not using any wallet sdks. I'm using Petra chromium extension and able to connect using window.aptos.connect().

When you retrieve the account from a browser extension, you will never get the account privateKey back as it a major security issue - imagine the wallet returns your account private key to any website that asks for it.

Therefore, when you interact with an extension wallet, only the wallet itself knows the connected account private key and can sign transaction on the account behalf.

If you want the wallet extension to sign / signAndSubmit transaction, you can use the wallet API .sign() or .signAndSubmitTransaction(). Best would be to work with the aptos-wallet-adapter tool as it handles the different wallet API interfaces and communication.

I don't want direct pkey access. I'm coming from working with EVM and Cosmos SDK for years where you can pass the signer down and then construct your transaction. No access to private keys, just the signer. Sudo code:

connectWallet()

signer = getSigner()
hash = client.signTx(signer, txPayload)

What I ended up doing is simply just passing down window.aptos to my SDK
