In the digital realm, ensuring that users have the right access to the right resources is paramount. This is where the concept of authorization scopes comes into play. In this introductory post, we'll explore what authorization scopes are, their significance, and get a glimpse of how Rollup ID leverages them to provide a secure and user-centric experience.

What are Authorization Scopes?

At its core, an authorization scope is a descriptor or identifier that defines a specific permission or set of permissions. Think of it as a label that represents a particular action or access level within an application. For instance, a scope might allow a user to read data, write data, or both.

In the context of OAuth 2.0 and OpenID Connect (OIDC), scopes are used to specify what access an application is requesting from a user. When a user grants permission, they're essentially allowing the application to act on their behalf within the limits of the specified scopes.

Why Are Authorization Scopes Important?

  1. Granular Access Control: Scopes allow applications to request precise permissions. Instead of giving blanket access, an application can ask for only what it needs, ensuring that users don't grant more permissions than necessary.
  2. Enhanced Security: By limiting permissions to what's necessary, scopes reduce potential damage in case of security breaches. If an attacker gains access to a token, they're restricted by its associated scopes.
  3. Transparency and Trust: When users see the exact permissions an application is requesting, they can make informed decisions about granting access. This transparency fosters trust between users and applications.

A Glimpse into Rollup ID's Use of Scopes

Rollup ID, as a modern identity solution, harnesses the power of authorization scopes to provide both security and flexibility. When applications integrate with Rollup ID, they can specify the scopes they need, ensuring that users always have a clear understanding of what they're consenting to.

Moreover, Rollup ID's decentralized approach to identity management means that users are always in control. They can see which applications have access to their data, what kind of access they have, and can revoke access at any time through the Rollup ID Passport.


Authorization scopes are a foundational concept in modern digital identity systems. They provide the necessary granularity, security, and transparency that both users and applications need. As we delve deeper into this series, we'll explore the intricacies of scopes in Rollup ID and how they play a pivotal role in creating a seamless and secure digital experience.
