## Start Login Test
{% hint style="warning" %}
Before you can start, you need to successfully complete the [registration test](/user-guides/registration-test.md).
{% endhint %}
1\) Click the **green "Authenticate" button** to start the login test of the connected SafeKey device.
2\) If you didn't complete the [registration test](/user-guides/registration-test.md) yet, you'll be asked to do that first.
3\) If you did successfully complete the [registration test](/user-guides/registration-test.md) already, clicking the **green "Authenticate" button** will work and **the login test will start**.
4\) **Touch your SafeKey** to verify the connected device.
5\) If the **login test is ready** and your SafeKey is working as expected, SafeKey Desktop Tool should show the message **"Success"** below the "Authenticate" button.
