Change password

You can also use the confirmPasswordReset method to confirm a password reset request. This method takes two arguments: the code from the password reset email and the new password.
Here is an example of how to confirm a password reset request:

firebase.auth().confirmPasswordReset(code, newPassword).then(() => {
  // Password reset confirmed and new password updated.
}).catch((error) => {
  // Handle Errors here.
});

Once the user's password has been reset, they will be able to sign in to their account with their new password.
