Enter Looty Bay Bank as a Civilian to create an account. To protect cash from theft, you will also need to process it through a Laundering Desk at your base. Opening the account alone is not the whole process.
Account first, base setup next
If you are coming from a robbery, leave the city to clear criminal status before returning in the Civilian role. Once you have an account, plan your base plot and laundering setup.
Understand the protection window
Laundering takes time. Processed funds are protected from theft until the next wipe, and cash can be withdrawn at an ATM. The official article does not give a universal processing rate, so this guide does not estimate completion time.
Protection from theft does not mean protection from the Federal Raid reset. Check the wipe tool before planning a long processing window.
