I would like to know my username and password.

Hi @Rossyg46

Thank you for contacting F-Secure.

Since you mention your subscription for F-Secure Freedome VPN made through Apple AppStore, the subscription can be only used within an iOS device with the same email address subscription. You may read the article below regarding F-Secure Freedome VPN subscription:

If you wish to have the F-Secure Freedome VPN on multiple devices, you will need to purchase the F-Secure Freedome VPN through our website.

My suggestion to you is to cancel and get a refund for the F-Secure Freedome VPN subscription through Apple AppStore and purchase the Multi-Device subscription from our website to maximize the subscription on several devices. Here is some article link for your reference:

Let me know if you have any other inquiry.
