Token based authentication works by ensuring that each request to a server is accompanied by a signed token which the 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 attributes and within the body of a POST request. Interested in getting up-to-speed with JWTs as soon as possible?

Token Based Authentication

The use of tokens has many benefits compared to traditional token required 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 header. The header consists of metadata including the type of token and the hashing algorithm used to sign the token.

User Access Tokens

The payload contains the token required data that the token is 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.

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. 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.

Matthew Langlois In Julywe announced our intent to require the use of token-based authentication for example, a personal access, OAuth, or GitHub App installation token for all authenticated Git operations. Token required August 13,we will no longer accept account passwords when authenticating Git operations on GitHub. If you use GitHub Enterprise Server, we have not announced any changes to our on-premises offering. Background We described our motivation as we announced similar changes to authenticating with the API as follows: In recent years, GitHub customers have benefited from a number of security enhancements to GitHub.

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 token required your server, for example, may not be common practice, but may be necessary to meet your requirements. To check token required 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.

Error Message

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 token required request. We used just the default settings to token required the capabilities of JWT but you can learn much more via the docs.
