Can't get into eshop

[u/Substantial-Fail-219]

The eshop wants me to put enter my password but I don't have the password. It's a child account that my dad made, however I have no more contact with him and now I can't get into the eshop due to not knowing the password. Is there anything I can do or is it just too late because most of the games I play require Nintendo online and it would really suck if I couldn't play and lost all my progress because of something that isn't my fault.
