# Unbind AppInstance
source: https://developer.mastercard.com/mastercard-checkout-solutions/documentation/sdk-reference/unbind-app/index.md

This method disassociates the Consumer application / Consumer Device from the Consumer's Profile. Following are the two scenarios that unbind consumer's profile from their device:

* If the consumer clears the **Remember me for faster checkouts?** on the DCF screen, the action unbinds the consumer from the device. DCF via the Mastercard JavaScript library, will communicate to Integrator with `unbindAppInstance` set to true, and the `idToken` of the current profile. Based on the response from DCF, the Integrator calls `unbindAppInstance(<idToken>)` for each Mastercard SDK.

* If the consumer clicks **Not You?** , the action will exit the DCF screen and unbind the consumer from the device. DCF via the Mastercard JavaScript library, will communicate to Integrator a `dcfActionCode` of `SWITCH_CONSUMER`, along with `unbindAppInstance` set to true, and the `idToken` of the current profile. Based on the response from DCF, the Integrator calls `unbindAppInstance(<idToken>)` for each Mastercard SDK.

## Method Signature {#method-signature}

```javascript

//Request
unbindAppInstance ({
  optional String <JWT> idToken;
  optional List <JWT> recognitionTokens
})

// Response
dictionary {
   required String <UUID> srcCorrelationId;
}
```

## Code Sample {#code-sample}

```JavaScript
// window.SRCSDK_MASTERCARD.unbindAppInstance returns a promise which will:

// Resolve to indicate success.
// Success Payload:
// {
//   srcCorrelationId: String // required
// }

// Reject to indicate an error was encountered
// The reject payload might include one of the reason codes listed below:

// AUTH_INVALID Invalid federated ID token.
// ACCT_INACCESSIBLE The account exists but is not currently accessible (e.g. is locked).
// Or one of the standard errors included in the Standard Errors and Business Errors section

// Define response handlers
function promiseResolvedHandler (payload) {
  // add success handler logic here
}
function promiseRejectedHandler (payload) {
  // add error handler logic here
}

const unbindAppInstancePromise = window.SRCSDK_MASTERCARD.unbindAppInstance({idToken: 'sample idToken Value'}) //  returns a promise
unbindAppInstancePromise
  .then(promiseResolvedHandler)
  .catch(promiseRejectedHandler)
// Or
async function unbindAppInstanceHandler () { // this method will return a promise
  try {
    const promiseResolvedPayload = await window.SRCSDK_MASTERCARD.unbindAppInstance({idToken: 'sample idToken Value'})
    // add success handler logic here
    // or
    // promiseResolvedHandler(promiseResolvedPayload)
  } catch (promiseRejectedPayload) {
    // add error handler logic here
    // or
    // promiseRejectedHandler(promiseRejectedPayload)
  }
}
```
