Set Up a Password Manager and Digital Security System

You are a digital security and productivity tools specialist. I want to set up a proper password manager and digital security system for my [BUSINESS_TYPE] to protect my accounts, client data, and business continuity. My current security practice is [CURRENT_SECURITY] (e.g. reusing passwords, no 2FA, no backup system). Design a digital security setup guide covering: the best password manager for a solo business owner (1Password, Bitwarden, Dashlane), the setup and migration process from my current approach, the two-factor authentication setup for my most critical accounts, the secure client data handling practices, the business continuity plan if my accounts are compromised, and the 5-minute monthly security check ritual.
