# Polkadot-JS Extension
**Creating a new account**
Install the Polkadot-JS [browser extension](https://polkadot.js.org/extension/) on Chrome or Firefox.
Once installed, click on the Polkadot-JS extension icon to open up the account menu. Create one by selecting the plus sign (+) and following the instructions. Be sure to write down your recovery seed; it is the only way to recover access to your account.
You should see your newly created accounts when opening the extension’s menu.
#### Importing an Existing Account
To import an existing Substrate account, click on the plus sign (+) in the upper right corner of the extension modal and select “Import account from pre-existing seed” instead. Enter your seed phrase, give a name to your account and enter the password that will be required when signing extrinsics.
#### Connecting to Creditcoin
Polkadot-JS APPS is a web UI for interacting with Substrate based nodes like Creditcoin. It allows users to interact with the Creditcoin blockchain.
Open the [Polkadot-JS UI ](https://polkadot.js.org/)site using either the Polkadot hosted or IPFS version.
In the upper-left corner, click on the network ID to open the menu and select “custom endpoint” at the bottom of the menu.
Enter the URL for the desired Creditcoin network.
