Google Inactive Account Manager

Google's Inactive Account Manager (IAM) allows you to designate "trusted contacts" who receive access to your Google data after a period of inactivity (3-18 months). It covers Gmail, Drive, Photos, YouTube, and other Google services.

Pros: Free, covers all Google services, integrated into your existing Google account.

Cons: Only covers Google data (not external credentials or files), minimum 3-month inactivity period, no encryption beyond Google's standard, Google has full access to the data.

ZeroLatch

ZeroLatch is a purpose-built dead man's switch with zero-knowledge encryption. You upload any files or text, encrypted client-side with AES-256-GCM. The service releases the encrypted vault to recipients when you stop checking in.

Pros: Zero-knowledge encryption, any file type, configurable intervals (days not months), anonymous registration, not limited to one ecosystem.

Cons: Requires uploading files specifically (doesn't automatically include your existing data), separate service to manage.

When to Use Each

Use Google IAM for: automatically sharing your Google-specific data with family after extended inactivity.

Use ZeroLatch for: securely sharing credentials, encryption keys, sensitive documents, and any non-Google data. When privacy from the service itself matters. When you need shorter intervals.

Best approach: Use both. Google IAM for your Google data, ZeroLatch for everything else. They serve complementary purposes.
