Sign In Applications

Once you have Sender installed, you'll be able to sign in and interact with the applications. 
Sign In
To interact with smart contracts, users need to sign in the application and request one function call key for the contract. Once sign in, the application will be authorized to call the change methods defined in the scope.  
// Sender will show a popup dialog to ask user to authorize your dApp
// This creates an access key that will be stored in Sender's storage
// The access key can then be used to connect to NEAR and sign transactions
​
await window.near.requestSignIn({
  contractId: "guest-book.testnet", // contract requesting access
});
​
// Or add `methodNames` if you only allow the key to call some of the methods
​
await window.near.requestSignIn({
  contractId: "guest-book.testnet", // contract requesting access
  methodNames: ["addMessage"]       // (optional) changed methods the app allowed to use
});
​
window.near.isSignedIn()   // true
​
Sign Out
You may want to remove the generated function access key from browser extension storage if you don't want to use the application any more. 
window.near.signOut();    // true
window.near.isSignedIn()   // false
