Greetings, explorer! Today, we are diving into the concept of tokenization in authentication. Tokens maintain user sessions and secure web applications. In this lesson, you will learn how to create, store, and send these tokens using axios without any third-party libraries.

Tokens provide crucial access rights in web applications. Much like a boarding pass for a spaceship, tokens confirm your identity and privileges. They are essential for making web apps efficient and secure. Tokens can be compared to VIP passes at concerts; present it once and you're granted widespread access!

Sure thing! Manual token creation doesn't necessitate any third-party modules. We can use built-in JavaScript methods to construct tokens manually. We'll piece together random values to create unique token-like strings.

While these are not cryptographically secure tokens like our previous examples, they do give elementary understanding on how to create unique identifiers manually.

In this function, we create a token by choosing a random character from charSet for times. The generated strings are likely to be unique, but unlike cryptographically-secure tokens, they have a non-zero chance of being guessed or duplicated through numerous attempts.
