If you ask when was jwt invented, the answer starts in late 2010. A group of web authors published the first JSON Web Token draft that December. The Internet Engineering Task Force later made it an official standard in May 2015. Before this change, web teams used heavy XML files to pass login data around. Those old XML files were large and hard to read on mobile devices.
Why knowing when was jwt invented matters for engineers and AI agents
To see why engineers ask when was jwt invented, look at web apps in 2010. Back then, phones and single-page apps started to replace older desktop web pages. Developers needed a small, fast way to send user claims between different servers. JSON was already popular with web developers because it worked well with JavaScript.
Each token has three distinct parts separated by dots in a single string. The first part is the header, which tells the server which signature math to use. The second part is the payload, which holds user facts like a role or email. The third part is the signature, which proves no one changed the data in transit.
Today, both human engineers and AI agents use these tokens to run tasks. A user or bot logs in once and gets a signed token back. Next, the client sends that token with every new request to an API or database. The server checks the signature with a secret key and trusts the claims inside. The server does not need to look up a session record in storage.
Security tradeoffs of stateless tokens during active sessions
Stateless tokens save server lookups, but they also create clear security risks for teams. Once an identity tool signs a token, that token stays valid until it expires. If an attacker steals a token, they can act as that user right away. You cannot cancel a standard token without building a custom block list on your server. Building a block list removes the main benefit of using stateless tokens in the first place.
Static roles inside a token also fail to control what happens during a live session. A token might prove who a user is when they first log in. Yet it cannot inspect the exact commands a user or AI agent runs next. An engineer with a valid token might still run a bad query that drops a table. An AI agent with a valid token might pull raw phone numbers or card numbers.

How teams manage token lifespans and runtime risk
Security teams try to limit token risk by making expiration times very short. Many teams set access tokens to expire after five or fifteen minutes of use. When the access token dies, the app uses a refresh token to get a new one. This setup helps, but a stolen token can still cause harm in five minutes.
Secret keys also create work for ops teams who run many cloud services. If you use one shared secret key, every server that checks tokens needs that key. If one server leaks that key, an attacker can forge tokens for any user. Public and private key pairs fix this issue, as servers only need the public key. Even so, teams still need to rotate keys and watch what happens inside active sessions. Token checks only guard the front door, not the data inside the system. Data masking can also help by rewriting matched fields like emails or national IDs in results.
Check database and API queries on the wire
Identity tools, roles, and network rules decide who opens a session. Setup alone cannot check what each query does or mask sensitive values in a response once a session starts. When workflows touch Postgres, MySQL, SQL Server, MongoDB, ClickHouse, Kubernetes APIs, SSH, or internal HTTP APIs, hoop.dev runs beside those services as an open-source proxy, a sidecar for your Postgres or API. It inspects requests coming in and results going back on the wire.
Your login details and client tools stay as they are while hoop.dev guardrails refuse bad deletes or drops before they run. On responses, hoop.dev data masking rewrites matched sensitive values in memory. Furthermore, hoop.dev holds SOC 2 Type II, is MIT licensed, and writes every query and decision to an audit trail that generates evidence for HIPAA, GDPR, and PCI DSS. See the source on GitHub.
Frequently asked questions
What year did JWT become an official internet standard?
The Internet Engineering Task Force published the final RFC 7519 standard in May 2015. That document came after five years of drafts and testing by major tech companies.
Why did developers switch from SAML to JSON Web Tokens?
SAML uses large XML files that are slow to parse on web browsers and phones. JSON tokens are much smaller, fit inside URLs, and work right away with JavaScript apps.
Can you revoke a JSON Web Token before it expires?
No, you cannot revoke a standalone token because the server only checks its math signature. To stop a token early, you must track blocked tokens in a fast server list.
