The simplest way to

Add GitHub Login to Your App

Your users are developers. They already have GitHub accounts and they expect to use them. The Bridge wires up GitHub OAuth (Open Authorization) in minutes, with no token handling and no session plumbing. Just a "Sign in with GitHub" button that works.

Quickstart in minutes

Enterprise-grade & compliant by default

OAuth handshake handledConsent, callback, and token exchange wired for you.
Minimal scopes by defaultEmail and profile only, add more when you need them.
One clean user objectSame user, every method, ready in every SDK.

Go live in a day

Turn it on. That's the setup.

GitHub login is a toggle, not a project. Flip the switch and the "Continue with GitHub" button appears in your sign-in screen instantly, with no redeploy.

Flip it, watch your login screen update live.

The fastest way to add it

Don't wire the OAuth. Describe it.

The Bridge is agent-native. Add our MCP (Model Context Protocol) server to your AI editor and ship GitHub login by asking.

Your agent does the wiring, you ship GitHub loginwiring

Connect your AI agent to The Bridge over MCP, then just ask. It enables GitHub in the Control Center, wires the consent and callback flow with minimal scopes, and drops the "Continue with GitHub" button into your login, correctly the first time.

Why GitHub login

The biggest wins, out of the box

For a developer tool, GitHub login is the sign-in your users already expect. It removes friction and credential risk at once.

The login devs expect

Your audience already lives in GitHub. One click and they are in, no new account to create.
UX
No passwords to store

GitHub verifies the user, so there is no password database to breach or reset.
Security
Minimal scopes by default

Email and profile only, so users trust the access they grant. Add scopes when you need them.
Trust
Same user, every method

GitHub, Google, magic link, and email all normalize to one consistent user schema.
Consistency
Higher conversion

Fewer fields and no signup friction mean more developers finish creating an account.
Growth
Standards-based

OAuth 2.0 and OpenID Connect under the hood, handled for you, not your problem.
Future-proof

And of course

First-class SDKs for every stack

Type-safe, batteries-included SDKs with drop-in components, and the same clean user object everywhere.

Rolling your own vs. The Bridge

What a hand-built GitHub OAuth integration actually costs you, versus a single toggle.

Building it yourself

Register a GitHub OAuth App and manage its credentials
Build the consent, callback, and token-exchange flow
Pick scopes carefully and parse GitHub's profile shape
Link GitHub identities to existing users by verified email

With The Bridge

Flip one toggle in the Control Center
Consent and callback flow handled, multi-tenant by default
Minimal scopes by default, expandable when needed
Same clean user object, every login method

Under the hood

What Adding GitHub Login Actually Involves

GitHub login is OAuth (Open Authorization) without the OpenID Connect (OIDC) layer. Here is how the flow works, what a manual build involves, and where The Bridge turns it into a toggle.

What adding GitHub login involves

Adding GitHub login means registering an OAuth App on GitHub, redirecting users to authorize, exchanging the returned code for an access token, and calling the GitHub API for the user's profile. Unlike Google, GitHub is not OpenID Connect, so there is no ID token to verify.

GitHub uses plain OAuth 2.0. You register an OAuth App, send the user to GitHub to authorize, and GitHub returns a one-time code. Your server exchanges that code for an access token, then calls the GitHub API to read the user's profile and email.

Because GitHub is not OIDC, there is no signed ID token and no email_verified claim. You read identity from the API instead, which changes how you confirm an email and link accounts.

For how this sits alongside sessions and roles, see the SaaS authentication guide. With The Bridge, GitHub login is a toggle on the hosted login box: paste your OAuth App client ID and secret, and the token exchange, profile lookup, and clean user object are handled for you.

How GitHub OAuth works under the hood

Your app redirects to GitHub with a client ID, scopes, and a state value. The user authorizes, GitHub returns a one-time code, and your server exchanges it for an access token. You then call the GitHub API for the profile, and the email endpoint when the user keeps their address private.

The flow is a standard OAuth exchange. You redirect to GitHub with your client ID, the scopes you need, and a random state value to protect the round trip. GitHub authenticates the user and redirects back with a code, which your server swaps for an access token over a back-channel request.

With the token you call the GitHub API. The profile endpoint gives you the account, but a user's primary email is often private, so you call the dedicated emails endpoint (/user/emails) to get a verified, usable address. Keep scopes minimal: read:user and user:email cover login without asking for repository access.

The Bridge runs this exchange and the email lookup for you, and normalizes the result into the same user object every other method returns.

OAuth App vs GitHub App, and a manual build

For login, you want a GitHub OAuth App. A GitHub App is for fine-grained repository and organization access, not sign-in. A manual login build then handles the token exchange, the private-email lookup, account linking without an email_verified claim, and safe token storage.

Pick the right primitive first. A GitHub OAuth App is the tool for sign-in. A GitHub App is a different thing, built for granular repository and organization permissions, and it is awkward overkill for plain login.

A manual build then owns the details: exchanging the code for a token, calling /user/emails to resolve a private primary email, and deciding how to confirm identity without an email_verified claim to lean on. You also store the access token safely if you keep it, and resist scope creep, since asking for repository scopes you do not need erodes user trust fast.

The Bridge handles the exchange, the email lookup, and the linking, and asks only for the minimal scopes login requires.

Production considerations

Keep a fallback for users without GitHub, link accounts by verified email so nobody gets a duplicate, and request the smallest scope set that works. GitHub login is the sign-in your developer audience expects, so the polish is in the account model, not the button.

Offer a second method. Your audience skews technical, but not everyone signs in with GitHub, so keep a fallback available. A natural pairing is to add Google login alongside it.

Link identities by verified email. If a user has signed in before with a different method on the same address, match them to the existing account instead of creating a new one.

Stay minimal on scopes. Email and profile are enough for login; add more only when a feature genuinely needs it, and tell the user why. With The Bridge, GitHub login defaults to minimal scopes and returns one consistent user object, the same as every other method.

Common questions

Do I need to register a GitHub OAuth App?

Yes. You create an OAuth App in GitHub and paste the client ID and secret into the Control Center. That is the only GitHub-side setup, and The Bridge handles everything after the redirect.

Which scopes does The Bridge request?

By default just the user's email and basic profile, the minimum needed to create an account. You can request additional scopes from the dashboard when a feature genuinely needs them.

What if a user has no public email on GitHub?

The Bridge requests the user's primary verified email through the GitHub API, so you still receive a valid address even when the user keeps it private on their profile.

Can users link GitHub to an existing account?

Yes. If someone signs in with GitHub using an email that already exists, The Bridge links the identity to the same user instead of creating a duplicate.
