+- Ensure `gopass` is installed and initialized on your system.
+- Secrets are managed using gopass's native commands; `gman` acts as a wrapper to interface with gopass.
+- Updates overwrite existing secrets
+- If no store is specified, the default gopass store is used and `gman sync` will sync with all configured stores.

+### Provider: `one_password`
+The `one_password` provider uses the [1Password CLI (`op`)](https://developer.1password.com/docs/cli/) as the backing

+- Optional: `vault` (string) to specify which 1Password vault to use. If omitted, the default vault is used.

+  - name: op
+    type: one_password
+    vault: Production          # Optional; if omitted, uses the default vault

+
+Authentication:
+- **Interactive**: Run `op signin` to sign in interactively.
+- **Service Account**: Set the `OP_SERVICE_ACCOUNT_TOKEN` environment variable for non-interactive/CI usage.
+- **Desktop App Integration**: If the 1Password desktop app is installed and configured, the CLI can use biometric
+  authentication (Touch ID, Windows Hello, etc.).
+
+Important notes:
+- Ensure the 1Password CLI (`op`) is installed on your system. Install instructions are at
+  https://developer.1password.com/docs/cli/get-started/.
+- Secrets are stored as 1Password Password items. The item title is the secret name and the `password` field holds the

+- **Deletions are permanent. Deleted items are not archived.**
+- `add` creates a new Password item. If an item with the same title already exists in the vault, `op` will create a
