This SDK snippet allows your end-user to reset their password after they have logged in to your applicaiton. It is mandatory that they input their `oldPassword` to change it. The `auth` reference used in the code snippet below is defined in the [auth instance page](https://docs.catalyst.zoho.com/en/sdk/web/v4/cloud-scale/authentication/get-auth-instance).

```javascript
catalyst.auth.changePassword(oldPassword,newPassword)

```

> **Note:** This SDK snippet is only available if you install Web SDK 4.3.0
