To interact with sessionStorage by using the Console:

1. In DevTools, select the Console tool. For example, press Esc to display the Quick View panel, which always includes a Console tab.

2. If you want to access the sessionStorage key-value pairs of a domain other than the page you're on, use the JavaScript contexts menu to change the JavaScript context of the Console:

   

   In this scenario, there would be multiple domains listed below top.

3. Enter sessionStorage JavaScript expressions in the Console:

   

   The above screenshot shows the following JavaScript expressions, and the resulting output:

   > sessionStorage.key(0)
   <· 'my-key-01'
   > sessionStorage.key(1)
   <· 'my-key-02'
   > sessionStorage.setItem("my-key-01", "efgh-5678")
   <· undefined
   > sessionStorage.getItem("my-key-01")
   <· 'efgh-5678'
   

   When you enter JavaScript assignment expressions by using the Console, the Key/Value pair table is updated.
