If you’ve ever logged into a website using your Google, Facebook, or Apple account, congrats — you’ve tangoed with OIDC and lived to tell the tale. OpenID Connect (OIDC) is like the VIP pass for modern authentication. It lets users prove who they are without inventing a new password every five minutes or remembering that one account they created in 2014. Let’s unpack this identity wizardry with wit, wisdom, and a wild art prompt at the end.
What is OIDC?
OpenID Connect (OIDC) is an authentication protocol built on OAuth 2.0. While OAuth handles authorization (i.e., “Do you have permission?”), OIDC answers the all-important question: “Who the heck are you?”
OIDC adds an ID layer to OAuth, letting applications verify users’ identities and get basic profile info via tokens. Think of it as OAuth’s extroverted sibling who introduces you at the party.

Is OIDC Still Relevant?
Absolutely. In fact, it’s more popular than that friend who always brings snacks to the party. OIDC is the go-to protocol for secure, standards-based authentication in modern web and mobile applications. Major platforms like Google, Microsoft, and Okta all use it.
What Is It Used For?
- Single sign-on (SSO) across platforms
- Letting third-party apps use your identity (e.g., “Sign in with Google”)
- Providing profile info in a standard, secure way
- Delegating authentication so you don’t have to store passwords (yay, security!)
Pros and Cons
Pros:
- Simplifies authentication across services
- Works with existing OAuth2 infrastructure
- Widely adopted and supported
- Token-based: stateless, fast, and scalable
Cons:
- Complexity increases with fine-tuned configurations
- Misconfigurations can lead to security issues
- Debugging token flows can feel like untangling earbuds from 2008
Strengths and Weaknesses
Strengths:
- Interoperability
- Scalability
- Built-in identity verification
Weaknesses:
- Requires solid token management
- Depends heavily on accurate time-sync (token expiration!)
- Not a panacea — still need to handle roles, MFA, etc.
Example in the Wild
Say you build a web app and want users to log in via their Google account. Instead of managing passwords (and angry support emails), you redirect users to Google, they log in, and you get back an ID token with their profile info. Boom — authenticated.
Alternatives to OIDC
- SAML: Older XML-based standard, widely used in enterprise SSO
- CAS: Central Authentication Service, simpler but less flexible
- LDAP: Not directly comparable but often used for internal identity storage
History & Inventor
OIDC was developed by the OpenID Foundation and released in 2014. It evolved from the original OpenID protocol and integrates seamlessly with OAuth2, designed specifically for the modern web and mobile era.
Who Uses It?
Just a few little-known startups like:
- Microsoft
- Amazon
- Apple
- IBM
- Salesforce
- Okta
- Auth0
And virtually any app using a “Sign in with…” button.
Popularity: Past, Present, and Future
Most popular around 2020–present as cloud-native architecture and microservices exploded.
Trend? Upward. If anything, it’s becoming more important as decentralized identity and zero-trust models take hold.
Does It Work With AI?
Yes! Especially when you build AI platforms or APIs that require secure user access. OIDC can be used to authorize users accessing:
- LLM dashboards
- API rate limits by user
- Cloud-based ML notebooks
- Admin portals for your AI models
Compatible Tech Stacks
Works with anything that can send HTTP requests:
- Node.js, Python, Java, Go, Rust
- React, Vue, Angular
- Mobile: iOS, Android
- Libraries:
oidc-client,authlib,passport.js,OpenIddict
Tools and Resources
Random But True
Is OIDC the subject of any famous art? No — but if Caravaggio were alive, he’d probably paint a dramatic scene of a user trying to debug a misconfigured redirect URI.
Any Other Tidbits?
- Tokens can be ID tokens (JWT), access tokens, and refresh tokens.
- The
nonceparameter is your BFF against replay attacks. - ID tokens can be signed (JWS) or encrypted (JWE).
Art Prompt: A fragmented, surreal Cubist portrait evoking digital identity — geometric forms of faces overlapping in profile and frontal view, layered with glowing token-like orbs, abstract circuits, and angular shadows. The composition should mirror the bold lines and shattered forms of a 1912 Cubist canvas, with a cool-toned palette of cobalt, slate gray, and electric green, conveying the tension between personal identity and abstraction.
Video Prompt: Create a fast-paced TikTok-style animation showing geometric faces shifting and morphing as tokenized orbs orbit their features. Use Cubist-style transitions with glitch overlays and stylized digital circuitry to represent the exchange of identity across digital systems.
Friday Night Joke:
A developer dies and arrives at the cloud. St. Peter says, “We use OIDC here. Present your token.” Dev: “Sure, here’s my JWT.”
Peter scans it. “Hmm… it’s missing aud, iat, and iss. You sure this isn’t a self-signed weekend hackathon job?” Dev: “Oh. Uh… maybe?”
Peter sighs. “To Hell with you.”
