Hello! @esenbock esenbock
Welcome to the LastPass Community.
Do you remember saved the password in your account?
You can access your account using a computer, then got all items and look for the item.
In case you save the item as a Wi-Fi, in your vault, left side panel you should be able to see a WI-FI menu.
Please let me know if you need additional help.
Greetings!
