The Problem with Traditional Authorisation Flow

Introduction

In today's digital landscape, authorisation is a crucial aspect of ensuring secure and seamless interactions between users and applications. OAuth 1 and 2 tokens play a vital role in this process, enabling users to grant access to their data without sharing sensitive information. However, the traditional approach to handling these tokens can lead to a suboptimal user experience, particularly when it comes to maintaining authorisation across sessions. In this article, we will explore the concept of persisting authorisation, focusing on the benefits of storing OAuth 1 and 2 tokens, and discuss strategies for implementing a robust and efficient solution.

The Problem with Traditional Authorisation Flow

When a user grants access to an application using OAuth 1 or 2, the application receives an authorisation token, which is typically valid for a short period. Upon expiration, the user is prompted to re-authorise the application, resulting in a less-than-ideal user experience. This can lead to:

Increased friction: Users are forced to re-authorise the application, disrupting their workflow and potentially leading to frustration.
Reduced engagement: The need to re-authorise can deter users from engaging with the application, ultimately impacting its adoption and retention.
Security risks: Inadequate handling of authorisation tokens can expose users to security risks, such as token theft or misuse.

Benefits of Persisting Authorisation

Persisting authorisation tokens offers several benefits, including:

Improved user experience: By storing authorisation tokens, users can enjoy a seamless experience, without the need for repeated authorisation.
Enhanced security: Persisting tokens reduces the risk of token theft or misuse, as the token is not transmitted with each request.
Increased efficiency: Applications can reduce the number of requests to the authorisation server, resulting in improved performance and reduced latency.

Implementing a Token Persistence Strategy

To persist authorisation tokens, you can employ the following strategies:

1. Add Absolute DateTime to Token Record

When storing an authorisation token, include an absolute DateTime value to track when the token was issued. This allows you to:

Track token validity: Determine the token's expiration date and time.
Monitor token age: Identify tokens that are nearing expiration or have already expired.

2. Add Local Store for Token

Implement a local store, such as a registry or database, to store authorisation tokens. This enables you to:

Cache tokens: Store tokens locally to reduce the number of requests to the authorisation server.
Load/refresh tokens: Retrieve tokens from the local store before initiating the complete authorisation flow.

3. Load/Refresh Tokens from Local Store

When the application starts, attempt to load or refresh tokens from the local store before initiating the complete authorisation flow. This ensures that:

Tokens are up-to-date: Tokens are refreshed or loaded from the local store, reducing the need for repeated authorisation.
User experience is improved: Users can access the application without being prompted to re-authorise.

Best Practices for Implementing Token Persistence

To ensure a robust and efficient token persistence strategy, follow these best practices:

Use a secure local store: Employ a secure local store, such as a encrypted database or registry, to protect tokens from unauthorised access.
Implement token validation: Validate tokens upon loading or refreshing to ensure they are still valid and have not been tampered with.
Monitor token expiration: Regularly check token expiration dates to prevent tokens from becoming invalid.
Handle token revocation: Implement a mechanism to handle token revocation, ensuring that tokens are removed from the local store when they are no longer valid.

Conclusion

Persisting authorisation tokens is a crucial aspect of enhancing security and user experience in applications that utilise OAuth 1 and 2 tokens. By implementing a robust token persistence strategy, you can improve user engagement, reduce security risks, and increase efficiency. Remember to follow best practices for implementing token persistence, including using a secure local store, implementing token validation, monitoring token expiration, and handling token revocation. By doing so, you can provide a seamless and secure experience for your users.

Recommendations for Future Development

To further enhance the token persistence strategy, consider the following recommendations:

Implement token caching: Cache tokens in memory to reduce the number of requests to the local store.
Use a distributed cache: Employ a distributed cache, such as Redis or Memcached, to store tokens across multiple nodes.
Integrate with identity providers: Integrate with identity providers, such as Google or Facebook, to leverage their token persistence mechanisms.
Develop a token revocation API: Create a token revocation API to enable applications to revoke tokens programmatically.

Frequently Asked Questions

In this section, we will address some of the most common questions related to persisting authorisation tokens.

Q: What is the primary benefit of persisting authorisation tokens?

A: The primary benefit of persisting authorisation tokens is to improve the user experience by reducing the need for repeated authorisation. This leads to increased user engagement and adoption.

Q: How do I determine the expiration date and time of an authorisation token?

A: You can determine the expiration date and time of an authorisation token by including an absolute DateTime value when storing the token. This allows you to track the token's validity and monitor its age.

Q: What is the difference between a local store and a distributed cache?

A: A local store is a storage mechanism that is specific to a single application or node, whereas a distributed cache is a storage mechanism that is shared across multiple nodes or applications. A distributed cache can be used to store tokens across multiple nodes, improving scalability and availability.

Q: How do I handle token revocation in a persisting authorisation token strategy?

A: To handle token revocation, you can implement a mechanism to remove tokens from the local store when they are no longer valid. This can be achieved by integrating with identity providers or by implementing a token revocation API.

Q: What are some best practices for implementing a token persistence strategy?

A: Some best practices for implementing a token persistence strategy include:

Using a secure local store to protect tokens from unauthorised access
Implementing token validation to ensure tokens are still valid and have not been tampered with
Monitoring token expiration to prevent tokens from becoming invalid
Handling token revocation to ensure tokens are removed from the local store when they are no longer valid

Q: Can I use a token persistence strategy with multiple identity providers?

A: Yes, you can use a token persistence strategy with multiple identity providers. This can be achieved by integrating with each identity provider's token persistence mechanism or by implementing a custom token persistence strategy that supports multiple identity providers.

Q: How do I handle token caching in a persisting authorisation token strategy?

A: To handle token caching, you can implement a caching mechanism that stores tokens in memory. This can be achieved by using a caching library or by implementing a custom caching mechanism.

Q: What are some recommendations for future development of a token persistence strategy?

A: Some recommendations for future development of a token persistence strategy include:

Implementing token caching to reduce the number of requests to the local store
Using a distributed cache to store tokens across multiple nodes
Integrating with identity providers to leverage their token persistence mechanisms
Developing a token revocation API to enable applications to revoke tokens programmatically

Conclusion

In this Q&A article, we have addressed some of the most common questions related to persisting authorisation tokens. By following best practices and implementing a robust token persistence strategy, you can improve user experience, reduce security risks, and increase efficiency in your applications.
