I'm sorry to say, but there is no password recovery option for the master password. Unfortunately, even with a password manager, there is still the one password you need to remember. I do hope you manage to figure it out.
Changing the sim on the phone shouldn't affect fs-key in any way. Are you maybe talking about f-secure mobile security and not fs-key? If you are talking about mobile security, I can try to redirect your question to another section of the forum.
Can you clarify what app you are talking about? This section of the forum is about fs-key, a password manager. I think you might be talking about mobile security, a security application for mobile with antivirus and theft.-prevention etc.
I alerted the moderators of your plight, I am certain your post will be moved to a more related section in the forum sometime soon and an awesome product expert will pick up your case.
@emperor I moved the whole thread to a more relevant board.
Concerning the problem at hand kindly refer to AniaC's post to contact Support, reset security code cases have to be handled outside of the F-Secure Community.
For alternative way to unlock your mobile, refer to the following post:
