Median Salary Expectations:

How statistics are calculated

We count how many offers each candidate received and for what salary. For example, if a MuleSoft with OAuth with a salary of $4,500 received 10 offers, then we would count him 10 times. If there were no offers, then he would not get into the statistics either.

The graph column is the total number of offers. This is not the number of vacancies, but an indicator of the level of demand. The more offers there are, the more companies try to hire such a specialist. 5k+ includes candidates with salaries >= $5,000 and < $5,500.

Median Salary Expectation – the weighted average of the market offer in the selected specialization, that is, the most frequent job offers for the selected specialization received by candidates. We do not count accepted or rejected offers.

Where is OAuth used?

Social Media Shenanigans

  • Folks blend OAuth quicker than their morning smoothie to log into apps using their Twitter or Facebook. No memory gymnastics needed for passwords!

The Great API Bazaar

  • Developers use OAuth as an all-access backstage pass to mingle with APIs like Google and Spotify, trading data like secret handshakes.

Corporate Spy Games

  • In the corporate jet-set world, OAuth acts as the suave gatekeeper, deciding which third-party apps get a peek at precious company data.

Remote Control for Gadget Junkies

  • Smart home aficionados employ OAuth to grant their apps control over their IoT gizmos, ensuring that only their phone can turn the lights disco mode.

OAuth Alternatives

OpenID Connect

A layer on top of OAuth 2.0 that allows clients to verify the identity of an end-user. Example: Sign in with Google.

// Example using OpenID Connect in Node.js with Passport
passport.use(new GoogleStrategy({
callbackURL: ""
function(accessToken, refreshToken, profile, done) {
User.findOrCreate({ googleId: }, function(err, user) {
return done(err, user);

  • Easier to implement with existing OAuth 2.0

  • Many large providers support it

  • Standardizes identity assurance

  • Less flexible than OAuth in non-identity scenarios

  • May require additional endpoint configuration

  • Higher complexity than OAuth alone

SAML 2.0

Security Assertion Markup Language. Enables SSO for secure and federated identity management. Used commonly in corporate environments.

// Example of SAML response assertion to be parsed by a service provider
<samlp:Response ...>
<saml:Assertion ...>
<saml:SubjectConfirmation ... />

  • Better for enterprise-level SSO

  • Strong security assertions

  • Widely adopted in large organizations

  • Complex to implement

  • Heavier payload than OAuth tokens

  • Can be less user-friendly

JWT (JSON Web Tokens)

Compact, URL-safe means of representing claims to be transferred between two parties. Example: Token authorization in APIs.

// Example of a JWT token in a HTTP Authorization header
Authorization: Bearer <token>
// Where <token> is a base64 encoded JSON object with claims

  • Lightweight and fast

  • Self-contained with all necessary information

  • Can be easily transmitted through URL, POST parameters, or inside HTTP headers

  • Requires careful management of secret keys

  • No built-in revocation mechanism

  • Sensitive to token leakage as it contains claims

Quick Facts about OAuth

The Grand Entrance of OAuth: The Protocol with Swagger

Let's time travel back to 2006, when blazers and big phones were cool, and OAuth was just a twinkle in Blaine Cook's eye. A lead dev at Twitter, Cook was scratching his head over secure API auth without exposing your precious passwords to the seedy world of third-party apps. Thus, OAuth was born, catapulting our digital lives into an era of "access without exposure" - think of it as a VIP pass to your data without handing over the keys to your house.

From OAuth 1.0 to 2.0: The Transformation Saga

Now, OAuth 1.0 was no slouch, but it did have a bit of a face-palm moment: complexities that could give a developer migraines. This clunky beast of a process was revamped with the finesse of a power makeover in 2012 to produce OAuth 2.0. This new hotshot strutted onto the digital catwalk with scalable permissions, mobile-friendly vibes, and versatility so slick it made developers weep with joy. It was akin to upgrading from a paper map to a GPS – suddenly navigating authentication was that much easier.

Patch it Up!

Bug fixes and patches in software are like the surprise onions in your burger; they're inevitable. OAuth has had its fair share of tweaks, improving security and squashing those pesky vulnerabilities. One notable patchwork is the addition of 'state' parameter in OAuth 2.0 which slaps a unique session token on every auth request. It's the digital equivalent of a secret handshake, ensuring that the person you're talking to isn't wearing a villainous mustache and a cloak.

GET /authorize?response_type=code&state=xyz&client_id=s6BhdRkqt3

Top 10 OAuth Related Tech

  1. JavaScript

    At the heart of many OAuth integrations lies the venerable JavaScript, the Swiss Army knife of the coding world, scurrying around web pages like a caffeine-powered squirrel. It’s not just for sprucing up your UI with flashy tricks; it's also pivotal for OAuth token shenanigans. Incorporate JavaScript, and your site's doing the two-step verification dance like it's Saturday night at the disco!

    const oauth2 = new OAuth2Client(CLIENT_ID, CLIENT_SECRET, REDIRECT_URL);
    oauth2.getToken(code, function(err, token) {
    if (!err) {

  2. Node.js

    Take a walk on the server side with Node.js, the cool cat that Java developers secretly wish they could hang with. Node.js lets you whisper sweet nothings to your server in JavaScript, allowing for OAuth flows that are smoother than a jazz solo. It's non-blocking, event-driven, and can handle a multitude of tokens without breaking a sweat.

    const { google } = require('googleapis');
    const oauth2Client = new google.auth.OAuth2(CLIENT_ID, CLIENT_SECRET, REDIRECT_URI);

    access_token: `ya29.a0AfH6SMB...`

  3. OAuth Libraries (Passport, OAuth.js)

    If authorizing APIs were a sport, these libraries would be the MVPs. Passport for Node.js is like a chameleon, blending into any social networking party with over 500 strategies. OAuth.js keeps it slick for the front-end. Breeze through OAuth without writing the boring bits—because, let’s face it, we’d all rather be coding the next viral app.

    const passport = require('passport');
    passport.use(new GoogleStrategy({
    clientSecret: GOOGLE_CLIENT_SECRET,
    callbackURL: ""
    }, (token, tokenSecret, profile, done) => {
    User.findOrCreate({ googleId: }, (err, user) => {
    return done(err, user);

  4. OpenID Connect

    Not to be confused with that thing your parents could never figure out on the TV remote. No, OpenID Connect is OAuth's chatty cousin who also moonlights as an identity layer. Using simple REST/JSON-based interoperability, OIDC can ID a user and tell you things you never knew you wanted to know. Just the ticket for when authentication is priority numero uno.

    const oidc = new Issuer({
    issuer: '',
    authorization_endpoint: '',
    token_endpoint: '',
    userinfo_endpoint: '',

  5. Postman

    When you need to charm an API into giving you tokens, Postman delivers—not in a uniform and a van, but with a slick interface that can simulate any OAuth flow without breaking a sweat. It takes the grunt work out of API testing, leaving developers more time for coffee breaks and contemplating the existence of semicolons.

  6. OAuth2 Proxy

    When you've got a service that needs protection but you're reluctant to hand over yet another login and password to your users, OAuth2 Proxy steps in as the bouncer. It's like having a beefy security guard for your web services, ready to authenticate via OAuth quicker than you can say “Did you see my ID already?”

  7. Auth0

    Want to handle OAuth without getting your hands dirty? Auth0 is like hiring an expert to do it all for you. It’s a powerhouse platform that manages your authentication needs more efficiently than a room full of bureaucrats. Except, you know, without the impending sense of doom.

    audience: '',
    scope: 'openid profile email'

  8. Okta

    It's like Auth0, but with a different three-letter name. Okta swings into the authentication scene with solutions that just work. And by “just work”, think less “thumping your electronics” and more “Hey, that was surprisingly easy!”.

  9. Amazon Cognito

    If Amazon were a country, Cognito would be its passport office. Providing a quick-and-easy way to add user sign-up, sign-in, and access control to your apps, Cognito even expands to federated identities, which is like having an international coalition of login providers.

  10. Spring Security

    For the Java crowd, Spring Security is akin to an overprotective parent—always concerned with who’s accessing what. It’s the cornerstone for securing Spring-based applications and doesn't skimp on OAuth2 features, offering robust shielding for your applications with minimal fuss.
