In this blog post, you can accomplish the same by encrypting your home folder. When encrypt your home folder, unauthorized users will also not be able to browse or access your home directories.
Encrypting your home folder may not be suitable for everyone in every environment so make sure you’re absolutely certain that you want to use this feature in Ubuntu before actually using it.
To get started encrypting your home directory, logon to Ubuntu and run the commands below.
sudo apt-get install ecryptfs-utils
Since your can’t be logged-in while encrypting your exiting home folder, you must create a temporary account and login with it. Then run the commands below to encrypt your home folder. Replace USERNAME with your account name.
sudo ecryptfs-migrate-home -u USERNAME
When you login as the temporary user, run the su command plus your username to run commands as you, since your account has root / admin rights. You’ll be prompted for your password.
su USERNAME
Replace USERNAME with the username of the account that has root / admin rights.
After that, encrypt your home folder by running the ecryptfs-migrate-home –u USERNAME command.
To create a user in Ubuntu, run the commands below.
sudo adduser USERNAME
To delete user in Ubuntu, run the commands below.
sudo deluser USERNAME
When you login, you’ll see the screen shot below giving you more information about your encrypted home folder.
