Why do we need token-based authentication?
The use of tokens has many benefits compared to traditional methods such as cookies. Tokens are stateless. The token is self-contained and contains all the information it needs for authentication. This is great for scalability as it frees your server from having to store session state.
Why do we use tokens?
A token is used to make security decisions and to store tamper-proof information about some system entity. While a token is generally used to represent only security information, it is capable of holding additional free-form data that can be attached while the token is being created.
What is token authentication?
Token-Based Authentication, relies on a signed token that is sent to the server on each request. … The token might be generated anywhere, hence your API can be called from anywhere with a single way of authenticating those calls. Mobile ready: when you start working on a native platform (iOS, Android, Windows 8, etc.)
Why do we use JWT tokens?
Information Exchange: JWTs are a good way of securely transmitting information between parties because they can be signed, which means you can be sure that the senders are who they say they are. Additionally, the structure of a JWT allows you to verify that the content hasn’t been tampered with.

Auth tokens work like a stamped ticket. The user retains access as long as the token remains valid. Once the user logs out or quits an app, the token is invalidated. Token-based authentication is different from traditional password-based or server-based authentication techniques.
How does a token work?
A token is a device that employs an encrypted key for which the encryption algorithm—the method of generating an encrypted password—is known to a network’s authentication server. … A token is assigned to a user by linking its serial number to the user’s record, stored in the system database.
How do I protect access token?
How to Protect Access Tokens
- Use Proof Key for Code Exchange (PKCE) when dealing with authorization grant flows;
- Use Dynamic Attestation Protection with a secure authorization middleman service when dealing with authorization grant flow;
- Not store the OAuth app credentials in the source code or elsewhere;

Are JWT tokens secure?
The contents in a json web token (JWT) are not inherently secure, but there is a built-in feature for verifying token authenticity. … There are two critical steps in using JWT securely in a web application: 1) send them over an encrypted channel, and 2) verify the signature immediately upon receiving it.
Why is JWT bad?
An unexpiring JWT can become a security risk. You are also trusting the token signature cannot be compromised. This can happen if you are using weak encryption, encryption that becomes vulnerable in the future, or having the the private keys compromised. This vulnerability doesn’t exist with sessions.
