The details of this article do not cover how to make your account more secure. For this, Apple provides a service called FileVault.

This technique explains how to use DMG as a secure container for your files.

Steps

1. 1 Create a new folder and put the files you want to put in the disk image there.
2. 2 Right-click (or CTRL-Click), click on the folder and select “Get Info” and remember the size of its contents.
3. 3Open Disk Utility (Applications> Utilities> Disk Utility)
4. 4 Click on the "New Image" icon to create a new disk image. Enter a name for the image, and select a size appropriate for the size of the folder you created in Step 2.
5. 5 Select the encryption type (128 or 256bit), set the Partition to "Single Partition - Apple Partition Map" and the format to "read / write disk image."Click the Create button.
6. 6 Create a complex password and enter it in the appropriate fields. Uncheck the "Remember password in my keychain" checkbox, as this reduces the security of your data. Click the "OK."
7. 7 Put the contents of the folder from Step 2 into the newly created disk image.
8. 8 Disconnect the disk by dragging its icon to the Trash. Also, in the Search Engine, you can click on Eject, next to the connected image.
9. 9 Each time you try to open the image, you will be prompted for a password.
