I always hear the word token, eg. request a token.
I usually replace that word with "key".
But what does it mean exactly?

someone who is included in a group to make people believe that the group is trying to be fair and include all types of people when this is not really true.
In general, a token is an object that represents something else, such as another object (either physical or virtual), or an abstract concept as, for example, a gift is sometimes referred to as a token of the giver's esteem for the recipient. In computers, there are a number of types of tokens.
In the business realm, we can define the token as: A unit of value that an organization creates to self-govern its business model, and empower its users to interact with its products, while facilitating the distribution and sharing of rewards and benefits to all of its stakeholders.
A token is a unit of information (as opposed to a unit of data witch could be an integer). It is the smallest chunk of data that composes information.
for instance, in a compiler tokenizer, the char array {'c', 'l', 'a', 's', 's'} would be a chunk of data composing the token "class" (Because a complete word is, in most cases, the smallest kind of information a compiler deals with).

It depends on what kind of "token" you're talking about.
If you're talking about a hardware token, it's a piece of hardware that gives each user an identification number. That number is then paired with their username/password to provide an extra level of authentication.
If you're talking about a software token, then it's simply a piece of identifying information that is given to you after you authenticate with a system.
Once you have a token, you can provide that token to the authentication system to prove that you're already an authenticated user.
