Encrypting home directory in Ubuntu 16.04 after install

I will be traveling so I decided to encrypt my home directory just in case my laptop is lost or stolen.

1. Log in as target user  
2. Install required packages
• sudo apt-get install ecryptfs-utils
3. Create a temporary admin user
4. Log out target user
5. Log in as temporary admin user
6. Encrypt target user home directory
• sudo ecryptfs-migrate-home -u target_user
7. Encrypt swap partition
• sudo ecryptfs-setup-swap
8. Log out temporary admin user
9. Log in as target user
10. Record encryption passphrase
• ecryptfs-unwrap-passphrase
11. Reboot then log in as target user. Check if everything is working.
12. Clean up by removing the backup folder and temporary admin user.
