I need OAuth login with redirect URIs and refresh tokens

Sure — OAuth login with redirect URIs and refresh tokens usually means you want:

1. Authorization Code flow for login
2. A registered redirect URI so the provider can send the user back to your app
3. Offline access / refresh tokens so your app can keep the user signed in without making them log in again frequently

Typical flow

1. User clicks “Sign in with X”
2. Your app sends them to the OAuth provider’s authorization endpoint with:
   • client_id
   • redirect_uri
   • response_type=code
   • scope=openid profile email offline_access (or provider equivalent)
   • state for CSRF protection
   • PKCE parameters if it’s a public client
3. User authenticates and consents
4. Provider redirects back to your redirect URI with an authorization code
5. Your backend exchanges that code at the token endpoint for:
   • access_token
   • refresh_token
   • optionally id_token if using OpenID Connect
6. When the access token expires, your backend uses the refresh token to get a new access token

Important notes

• Redirect URI must match exactly what is registered with the provider.
• Use Authorization Code + PKCE for mobile, SPA, and other public clients.
• Store refresh tokens securely:
  • server-side if possible
  • encrypted at rest
  • never expose them to JavaScript in a browser if you can avoid it
• Rotate refresh tokens if the provider supports it.
• Always validate:
  • state
  • token issuer
  • audience/client ID
  • expiration

Example authorization request

GET https://provider.example.com/oauth2/authorize?
  client_id=YOUR_CLIENT_ID&
  response_type=code&
  redirect_uri=https%3A%2F%2Fyourapp.com%2Fauth%2Fcallback&
  scope=openid%20profile%20email%20offline_access&
  state=RANDOM_CSRF_TOKEN&
  code_challenge=...&
  code_challenge_method=S256

Example token exchange

POST https://provider.example.com/oauth2/token
Content-Type: application/x-www-form-urlencoded

grant_type=authorization_code&
client_id=YOUR_CLIENT_ID&
code=AUTHORIZATION_CODE&
redirect_uri=https://yourapp.com/auth/callback&
code_verifier=YOUR_PKCE_VERIFIER

Refresh token request

POST https://provider.example.com/oauth2/token
Content-Type: application/x-www-form-urlencoded

grant_type=refresh_token&
client_id=YOUR_CLIENT_ID&
refresh_token=YOUR_REFRESH_TOKEN

If you want, I can help with any of these next:

• a full implementation in Node.js / Express
• Next.js, React, Python, Spring Boot, or Go
• setting up Google, Microsoft, GitHub, Auth0, or Keycloak
• securing refresh tokens with cookies or server sessions

If you tell me your stack and identity provider, I can give you exact code.
