Language is the foundation of effective communication, yet in the tech world, we sometimes trip over the very words meant to clarify complex concepts. One of the perennial debates revolves around the term ‘auth,’ a shorthand used to refer generally to both authentication (authn) and authorization (authz). This practice has led to confusion and miscommunication, particularly among those new to the industry or those for whom English is not a first language. Is it time for us to reconsider the way we label these crucial processes?
Consider the terms ‘login’ and ‘permissions.’ These simple, straightforward words might serve as better substitutes for ‘authentication’ and ‘authorization,’ respectively. The argument in favor of this switch is compelling. When you tell a layperson to ‘log in,’ they understand that they need to prove their identity. Conversely, saying someone has ‘permissions’ makes it clear they are allowed to perform certain actions. But is it really that simple?
Critics argue that ‘login’ and ‘permissions’ may oversimplify complex processes. For instance, ‘authentication’ covers more than just logging into a system. It includes token-based authentication, API keys, and other advanced techniques. Similarly, ‘permissions’ represent only a subset of what authorization truly entails. Authorization includes fine-grained control over what a user can do, often governed by intricate policies. These policies could include time-based restrictions, geo-fencing, and even behavioral analytics. Simplifying these terms might strip away essential nuances.
The comments section of a recent article advocating for this change provides a robust debate on the subject. For example, using the term ‘permissions’ could muddy the waters further, particularly if permissions are seen as a subset of authorization rather than a replacement. Commenters like ‘verdverm’ and ‘candiddevmike’ point out that industry-standard terms like ‘AuthN’ and ‘AuthZ’ already exist to provide clarity. Less precise terminology could lead to a net increase in confusion, especially among seasoned professionals.
‘Login’ is another term that doesn’t quite fit neatly into the new paradigm. Typically, logging in is just one part of the broader authentication process, often involving things like generating and passing bearer tokens, especially in API-based systems. As ‘klabb3’ mentions, modern systems often operate on stateless protocols like HTTP, where each interaction demands fresh authentication. Calling this process ‘login’ is a stretch, as it suggests a stateful interaction that is not always there.
Yet, proponents like ‘dowagerdave’ and ‘jameshart’ suggest this language shift could solve real issues. For people outside the technical bubble, jargon can be a significant barrier. If the primary aim is inclusivity and accessibility, then reducing the cognitive load associated with these terms is worth considering. A language that is technically accurate yet accessible could bridge the gap between developers and end-users, fostering better understanding and collaboration.
However, as ‘jmsgwd’ and ‘danielmarkbruce’ argue, the push for simplicity shouldn’t come at the cost of precision. Technical accuracy is crucial, not merely for developers but also for the end-users who need to trust these systems. Think of a scenario where an audit trail goes awry due to a misinterpreted term. ‘Permissions’ can be easily misinterpreted during both development and auditing, leading to potentially grave security issues. One solution is to offer layered terminology: simple, accessible terms for general communication and the precise, technical terms for specialized contexts.
In conclusion, while the idea of switching to simpler terms like ‘login’ and ‘permissions’ has merit, it is not a one-size-fits-all solution. These terms are easier to understand but fall short of capturing the full scope of modern authentication and authorization processes. Striking a balance between simplicity and precision is essential for effective communication. Offering additional context and explanations rather than new terminology might be the better way forward. As we move towards more inclusive and user-friendly systems, let’s not forget the importance of clarity, accuracy, and the fine line between them.
