# Signer: Connect Keeper on website

To enable access to your web app via Keeper Wallet, use Signer.

![](/files/YdknhKdHWQ491urVfzb2)

Signer is a TypeScript/JavaScript library designed to sign and submit transactions on behalf of a user in any browser. The user can review details of each transaction and then confirm or reject it.

Signer implements a unified interface for interacting with signature provider libraries. You just initialize the libraries in your app and then use Signer functions to obtain signatures for transactions or arbitrary messages.

Keeper Wallet maintains the following signature providers:

* [ProviderKeeper](/connect-web-app/signer/provider-keeper.md) generates signatures via Keeper Wallet browser extension.
* [ProviderKeeperMobile](/connect-web-app/signer/provider-keeper-mobile.md) generates signatures via Keeper Wallet mobile app.

Refer to the [documentation](https://docs.waves.tech/en/building-apps/waves-api-and-sdk/client-libraries/signer) for details on Signer installation and functions.
