Contact Us Token Based Authentication A token is a piece of data that has no meaning or use on its own, but combined with the correct tokenization system, becomes a vital player in securing your application. Token based authentication works by ensuring that each request to a server is accompanied by a signed token which what does token mean server verifies for authenticity and only then responds to the request.
JWT has gained mass popularity due to its compact size which allows tokens to be easily transmitted via query strings, header q opton binary options overview and within the body of a POST request.
Interested in getting up-to-speed with JWTs as soon as possible? The use of tokens has many benefits compared to traditional methods such as cookies.

Tokens are stateless. Fine-grained access control. The header and payload are Base64 encoded, then concatenated by a period, finally the result is algorithmically signed producing a token in the form of what does token mean. The header consists of metadata including the type of token and the hashing algorithm used to sign the token.
The payload contains the claims data that the token what does token mean encoding. What this means is that a token can be easily decoded and its contents revealed.

If we navigate over the jwt. The server would attempt to verify the token and, if successful, would continue processing the request.
A token is an instance of a sequence of characters in some particular document that are grouped together as a useful semantic unit for processing. A type is the class of all tokens containing the same character sequence. A term is a perhaps normalized type that is included in the IR system's dictionary. The set of index terms could be entirely distinct from the tokens, for instance, they could be semantic identifiers in a taxonomy, but in practice in modern IR systems they are strongly related to the tokens in the document. However, rather than being exactly the tokens that appear in the document, they are usually derived from them by various normalization processes which are discussed in Section 2.
If the server could not verify the token, the server would send a Unauthorized and a message saying that the request could not be processed as authorization could not be verified. Keep it secret.
Why Use Tokens?
Keep it safe. The signing key should be treated like any other credentials and revealed only to services that absolutely need it. Do not add sensitive data to the payload. Tokens are signed to protect against manipulation and are easily decoded.

Add the bare minimum number of claims to the payload for best performance and security. Give tokens an expiration. Technically, once a token is signed — it is valid forever — unless the signing key is changed or expiration explicitly set.
Do not send tokens over non-HTTPS connections as those requests can be intercepted and tokens compromised. Consider all of your authorization use cases. Adding a secondary token verification system that ensure tokens were generated from your server, for example, may not be common practice, but may be necessary to meet your requirements. To check the contents our token, we can decode it at jwt.

The simplest way to do this is to use an app like Postman which simplifies API endpoint testing. When the call is made the jwtCheck middleware will examine the request, ensure it has the Authorization header in the correct format, extract the token, verify it and if verified process the rest of the request.
We used just the default settings to showcase the capabilities of JWT but you can learn much more via the docs. Mobile Apps — implementing native or hybrid mobile apps that interact with your services.
Home : Technical Terms : Token Definition Token Besides those small shiny coins that allow you to play video games, there are three different types of tokens: 1. In networking, a token is a series of bits that circulate on a token-ring network. When one of the systems on the network has the "token," it can send information to the other computers. Since there is only one token for each token-ring network, only one computer can send data at a time.
