What Does Auth0 Do for Your Bubble App?
Bubble has built-in authentication. It handles email/password sign-ups, password resets, and basic session management. So why would you add Auth0? Because enterprise clients and security-conscious users expect more. Auth0 gives you single sign-on (SSO) with SAML and OAuth providers, multi-factor authentication (MFA), social logins (Google, GitHub, LinkedIn), passwordless magic links, and advanced user management features like role-based access control.
If you're building a B2B SaaS product in Bubble and your customers need to log in with their company's identity provider — Okta, Azure AD, Google Workspace — Auth0 is the standard way to make that happen. It acts as a middleware layer between your Bubble app and dozens of identity providers, so you don't need to implement each protocol individually.
Real Use Cases for Auth0 in Bubble
The first and most common use case is enterprise SSO. Your B2B customer wants their employees to log in to your Bubble app using their existing corporate credentials. Without Auth0, you'd need to implement SAML or OpenID Connect directly in Bubble, which is technically possible but extremely painful. Auth0 handles the protocol negotiation and gives you a standardized token you can work with.
The second use case is social login aggregation. You want users to sign up with Google, Apple, LinkedIn, and GitHub. Bubble supports Google login natively, but adding other providers requires either individual plugins or a unified solution like Auth0. With Auth0, you configure each provider once in their dashboard and your Bubble app only talks to one authentication endpoint.
The third use case is MFA enforcement. If you're building in healthcare, finance, or legal tech, MFA isn't optional — it's a compliance requirement. Auth0 lets you enforce MFA globally or conditionally (for example, only when users log in from a new device) without building any of that logic in Bubble.
How to Set Up Auth0 with Bubble
The integration uses OAuth 2.0, which Bubble's API Connector supports natively through its "OAuth2 User-Agent Flow" authentication type. Start by creating an Auth0 account and setting up a new Application of type "Regular Web Application" in the Auth0 dashboard.
In Auth0's application settings, note your Domain, Client ID, and Client Secret. Set the Allowed Callback URLs to your Bubble app's OAuth callback URL, which follows the format: https://yourapp.bubbleapps.io/api/1.1/oauth_redirect. Also add your custom domain variant if you're using one.
In Bubble's API Connector, create a new API with Authentication type set to "OAuth2 User-Agent Flow." Enter the following values: the Authorization URL is https://YOUR_AUTH0_DOMAIN/authorize, the Token URL is https://YOUR_AUTH0_DOMAIN/oauth/token, and the User Profile URL is https://YOUR_AUTH0_DOMAIN/userinfo. Paste your Client ID and Client Secret from Auth0.
For the scope parameter, use "openid profile email" at minimum. This tells Auth0 to return the user's basic profile information and email address in the token response. If you need additional claims, add custom scopes in Auth0's API settings.
Once configured, Bubble will show an "Auth0" login option that you can trigger from any workflow using the "Signup/login with a social network" action. When a user clicks it, they're redirected to Auth0's Universal Login page, authenticate there, and get redirected back to your Bubble app with their session established.
Mapping Auth0 Users to Bubble Users
When a user authenticates through Auth0, Bubble creates a new user record or matches an existing one based on email. The tricky part is syncing additional user data from Auth0 into Bubble. Auth0's user profile can contain metadata like roles, permissions, organization membership, and custom attributes that you've configured in Auth0 Rules or Actions.
To access this data, you need to call Auth0's Management API from Bubble's backend workflows. Set up a separate API Connector entry for the Management API with machine-to-machine authentication. Create an M2M application in Auth0, grant it access to the Management API with the scopes you need (read:users, read:user_metadata), and use the client credentials flow to get an access token.
With this token, you can call endpoints like /api/v2/users/{user_id} to fetch detailed profile data and sync it to your Bubble database. Schedule this as a backend workflow that runs after each successful login to keep user data fresh.
Common Pitfalls with Auth0 and Bubble
The most frequent issue is callback URL misconfiguration. Auth0 is strict about allowed callback URLs. If your Bubble app uses both bubbleapps.io and a custom domain, you need both URLs in Auth0's allowed list. During development, you also need your Bubble test environment URL (with the /version-test path). Missing any of these means users hit an error screen after authentication.
Token expiration is another pain point. Auth0 access tokens expire (default is 24 hours, but configurable). If your Bubble app tries to use an expired token to call Auth0's API, the call fails silently in many cases. Implement token refresh logic in your backend workflows or set longer token lifetimes in Auth0's API settings for your Bubble application.
Session management conflicts can also cause confusion. Bubble manages its own session cookies, and Auth0 manages its own. If a user logs out of your Bubble app but not Auth0, they might get automatically logged back in on their next visit because Auth0's SSO session is still active. To handle this properly, trigger an Auth0 logout by redirecting users to your Auth0 logout URL when they log out of Bubble.
Lastly, watch out for the user duplication problem. If a user first signs up with email/password in Bubble, then later tries to log in via Auth0 with the same email through a social provider, Bubble might create a duplicate user. You need Auth0 Rules or Actions to handle account linking, or build a post-login workflow in Bubble that merges duplicate accounts based on email address.
DIY vs Hiring a Bubble Developer
Basic Auth0 integration — social logins and SSO — is achievable for most intermediate Bubble builders in about a week. The OAuth flow is well-documented on both sides, and the API Connector setup is straightforward once you understand the token exchange.
Where it gets complicated is enterprise SSO configurations (each customer might use a different identity provider), MFA policies, and proper session management across Auth0 and Bubble. If your product needs to support multiple SSO connections dynamically — common in B2B SaaS — the Auth0 Organizations feature adds another layer of configuration that's worth outsourcing to someone who's done it before.
Role-based access control is another area where experienced help pays off. Mapping Auth0 roles and permissions to Bubble's privacy rules requires careful architecture to ensure data security while maintaining performance.

Auth0 Makes Bubble Enterprise-Ready
Auth0 fills the authentication gaps that Bubble's built-in system can't cover. SSO, MFA, social logins, and advanced user management become configuration problems instead of engineering problems. The OAuth 2.0 setup is straightforward, but enterprise edge cases around session management and account linking need careful handling. Talk to our Bubble developers.

Frequently Asked Questions (FAQs)
Can I use Auth0's free tier with Bubble?
Yes. Auth0's free tier supports up to 7,500 active users and includes social logins, MFA, and basic SSO. This is enough for most early-stage Bubble apps. Enterprise features like custom domains and advanced SAML configurations require paid plans.
Does Auth0 replace Bubble's built-in authentication?
It augments it. Bubble still manages user sessions and database records. Auth0 handles the authentication flow itself, including identity verification, MFA challenges, and SSO protocol negotiation. Users authenticated through Auth0 still appear as regular Bubble users in your database.
How do I handle logout properly with Auth0 and Bubble?
You need to log the user out of both systems. In your Bubble logout workflow, first call Auth0's logout endpoint by redirecting to https://YOUR_DOMAIN/v2/logout with your client_id and a returnTo URL. Then run Bubble's native logout action. This prevents automatic re-login from Auth0's persistent session.
Can Auth0 handle role-based access control in Bubble?
Auth0 can manage roles and permissions, but you need to sync them to your Bubble database. Use Auth0 Actions to include roles in the ID token, then read those roles in a post-login Bubble workflow and store them on the user record. Use Bubble's privacy rules to enforce access based on those stored roles.
Is Auth0 integration in Bubble HIPAA compliant?
Auth0 offers HIPAA-eligible environments on their Enterprise plan, and they'll sign a BAA. However, HIPAA compliance depends on your entire stack, not just authentication. Your Bubble app, database configuration, and hosting also need to meet HIPAA requirements. Auth0 is one piece of the compliance puzzle.
How long does Auth0 integration take in Bubble?
Basic social login integration takes two to three days. Adding enterprise SSO with multiple identity providers takes one to two weeks. A full implementation including MFA, role syncing, proper session management, and account linking typically takes two to three weeks if you're doing it yourself.
