### React Component for Account Creation

Source: https://github.com/algorand/code-samples/blob/master/react-app-acct-txn-msig-assetoptin/README.md

A React functional component that renders a button. Clicking the button triggers the generation of a new Algorand account using the algosdk library and passes the generated key pair to a parent component via a prop.

```JavaScript
const CreateAccountButton = props => {
  // this will create a new account and push it to props createAccount
  let generateAccount = () => {
    // generating new account
    let keys = algosdk.generateAccount();

    // calling the props createAccount
    props.createAccount(keys);
  };

  return (
    <button
      type="button"
      className="btn btn-outline-primary col-md-12"
      onClick={generateAccount}
    >
      Generate Account
    </button>
  );
};
```

```JavaScript
// create opt-in transaction
      let opttxn = algosdk.makeAssetTransferTxn(recoveredAccount.addr, recoveredAccount.addr, undefined, undefined,
        params.fee, 0, params.lastRound, endRound, undefined, params.genesishashb64, params.genID, assetID);
```

--------------------------------

### React Component for Account Recovery

Source: https://github.com/algorand/code-samples/blob/master/react-app-acct-txn-msig-assetoptin/README.md

A React functional component that renders a button. When clicked, it uses the algosdk library to convert a provided mnemonic string into an Algorand secret key pair, passing the result to a parent component via a prop.

```JavaScript
const RestoreAccountButton = props => {
  // this will create a new account and push it to props createAccount
  let restoreAccount = () => {
    // generating new account
    var keys = algosdk.mnemonicToSecretKey(props.mnemonic);

    // calling the props createAccount
    props.restoreAccount(keys);
  };

  return (
    <button
      type="button"
      className="btn btn-outline-light col-md-12"
      onClick={restoreAccount}
    >
      Restore Account
    </button>
  );
};
```
