What is UUID?
A universally unique identifier (UUID) is a 128-bit number used to identify information in computer systems. The term globally unique identifier (GUID) is also used, typically in software created by Microsoft.
What is UUID used for?
UUIDs are generally used for identifying information that needs to be unique within a system or network thereof. Their uniqueness and low probability in being repeated makes them useful for being associative keys in databases and identifiers for physical hardware within an organization.
How do I find my UUID?
You can find the UUID of all the disk partitions on your Linux system with the blkid command. The blkid command is available by default on most modern Linux distributions. As you can see, the filesystems that has UUID are displayed.
Is UUID safe?
Many UUID generators use a version 4 random number. However, many of these use Pseudo a Random Number Generator to generate them. If a poorly seeded PRNG with a small period is used to generate the UUID I would say it's not very safe at all. Therefore, it's only as safe as the algorithms used to generate it.
