Parity comes with a built-in wallet. To access [Parity Wallet](http://web3.site/) simply go to http://web3.site/ (if you don't have access to the internet, but still want to use the service, you can also use http://127.0.0.1:8180/). It includes various functionality allowing you to:

includes various functionality allowing you to:
- create and manage your Ethereum accounts;
- manage your Ether and any Ethereum tokens;
- create and register your own tokens;
- and much more.
By default, Parity will also run a JSONRPC server on `127.0.0.1:8545`. This is fully configurable and supports a number
of RPC APIs.
