Proposal: A Universal “Login with Your Q2A Community” Authentication System

Question

Hello everyone,

I would like to explore a potential idea with the community that could expand the usefulness of Q2A forums beyond their current role as standalone Q&A platforms.

The concept is to allow Q2A communities to act as authentication providers for external websites and applications. In practical terms, this would allow developers to integrate a button such as:

“Login with Your Community Forum”

This concept is similar to authentication systems provided by platforms such as Google, GitHub, or Facebook, where users can log in to different applications using an existing account.

In this case, the authentication source would be a Q2A community account.

Before moving forward with development, I would appreciate the community’s feedback on the best architectural approach.

Approach 1: Standalone Authentication Plugin

One option is to develop a standalone Q2A plugin that forum administrators can install directly on their site. The plugin would expose the necessary API endpoints to allow external platforms to authenticate users through that forum.

Advantages

Everything runs locally on the forum

No dependency on an external service

Straightforward architecture

Potential Concerns

The plugin source code would be fully accessible after installation

Authentication logic could potentially be analyzed and exploited if not implemented carefully

Security maintenance and updates might be difficult to coordinate across many installations

Approach 2: Centralized Authentication Platform + Connector Plugin

An alternative approach would be to build a centralized authentication platform (for example: examplesite.com) combined with a lightweight connector plugin for Q2A forums.

In this model:

Forums install a connector plugin

The plugin securely connects the forum to the central authentication API

External developers integrate a single standardized authentication system that works with multiple Q2A communities

Example Login Flow

A user clicks “Login with Community” on an external website or application

A window opens displaying a searchable list of available communities

The user searches for their forum and selects it

The user connects their community account by logging in to authorize the connection (this step only happens once)

After the initial authorization:

The system remembers the selected community

The login button will display:

“Login with [Community Name]”

A “Change Community” option can also be provided so the user can select a different forum if needed.

This approach ensures that users do not need to search for their forum every time they log in.

Potential Benefits for the Q2A Ecosystem

Such a system could offer several benefits:

A standardized authentication method for Q2A communities

Increased visibility and integration opportunities for forums

Easier integration with other applications, scripts, and developer platforms

Possibility of future features such as cross-community identity or reputation systems

Project Sustainability

To initiate the project, I am willing to:

Develop the initial implementation

Cover the first year of hosting and domain costs

After that period, the community could determine the most appropriate way to maintain the platform. Possible approaches could include:

Community donations

A small contribution per forum (for example $1 per community) with unlimited API usage

The goal is to build something useful and sustainable for the Q2A ecosystem, rather than a purely commercial product.

Request for Feedback

I would greatly appreciate the community’s input on the following:

Which architectural approach would you prefer?

Option 1: Standalone plugin per forum

Option 2: Centralized authentication platform with a connector plugin

Are there any security considerations or architectural improvements that should be taken into account?

Would this type of authentication system be useful for your own Q2A community?

If there is interest from the community, I would also welcome collaborators and developers who would like to contribute to building a robust and secure implementation.

Thank you for your time and feedback.

Comments

This is my personal opinion.

I don't think, such plugin requirement. Because each Q2A site has it's own purpose. Hardly there are users who use more than one Q2A site.

So, for such low utilisation, one should not invest much time.

Thank you for your perspective, I appreciate it.

You are correct that most users typically participate in only one Q2A community. However, the intention of this idea is not mainly about users belonging to multiple forums. The goal is to allow a forum account to be used as an identity outside the forum.
For example, developers could add “Login with [Community Name]” to their applications, tools, or services. This would allow members of a Q2A community to access external platforms using their existing forum account instead of creating new accounts.

In that sense, the forum becomes more than a discussion site — it becomes an identity provider for its community. This could help extend the ecosystem around Q2A communities and make them more valuable beyond just the forum itself.
Of course, whether it is worth building depends on community interest, which is why I wanted to open the discussion here.

Thank you again for sharing your thoughts.

Just to clarify, this is currently only an idea and an open discussion. My goal is mainly to see whether there are other developers who might find the concept interesting and would be willing to explore it together.
If there is interest, we could collaborate and build something useful for the Q2A ecosystem. If not, I may still build a working example independently to demonstrate how it could work in practice. In that case, it would likely include limited free features with some premium options to support hosting and maintenance.
For now, I am simply trying to understand whether there are like-minded developers in the community who would be interested in experimenting with such a system.
