Authentication

Authentication in Bubble is the process of verifying a user's identity before allowing them to access your application. It covers sign-up, login, and session management.

Without authentication, your app cannot know who is using it or keep their data separate. It is the foundation of any multi-user application built on Bubble.

Key Takeaways

• Identity verification: Authentication confirms who a user is before giving them access to protected parts of your app.
• Built into Bubble: Bubble includes a native authentication system for email and password login out of the box.
• Third-party options: You can add Google, Facebook, or other OAuth providers using Bubble plugins.
• Session-based: Once authenticated, Bubble maintains the user's session so they stay logged in across page visits.

What is Authentication in Bubble?

Authentication in Bubble is the system that verifies a user's identity and creates a session for them in your app. Bubble has built-in support for email and password authentication. You can also add social login options like Google or Facebook using plugins.

Every Bubble app with user accounts relies on authentication to know who is who.

• Sign-up and login workflows: Bubble provides built-in workflow actions for creating accounts and logging in users securely.
• Password encryption: Bubble encrypts passwords automatically. You never have access to a user's raw password.
• Current User reference: Once logged in, Bubble tracks the user as "Current User" so you can display their data throughout the app.

Authentication is what makes personalization, privacy, and user-specific data possible inside a Bubble app.

How Authentication Works in Bubble

Bubble's authentication system works through built-in workflow actions. When a user submits a login form, a "Log the user in" workflow action checks their credentials against the database. If they match, Bubble creates a session and the user gains access to protected content.

The technical complexity is handled by Bubble. Your job is to design the login experience and connect the right workflows.

• Sign-up action: Use the "Create an account" workflow action to register new users with an email and password.
• Log in action: The "Log the user in" action checks credentials and starts a session when they match.
• Log out action: The "Log the user out" action ends the session and redirects the user to a public page.

Bubble also sends password reset emails automatically when users request them, which is another part of the authentication system you get without building it yourself.

Why Authentication Matters for No-Code Apps

Without authentication, every user who visits your app sees the same thing. Authentication is what turns a static website into a dynamic application. It enables personalized dashboards, private data, and role-based features that make real products work.

Most business apps are useless without knowing who is using them.

• Personalized experience: Show each user their own data, tasks, and settings based on their account.
• Data protection: Keep user records private so one user never accidentally sees another's information.
• Access control foundation: User roles and permissions are only meaningful after authentication confirms who the user is.

Authentication is not optional for serious apps. It is step one of building any product that serves individual users.

Third-Party Authentication in Bubble

Bubble supports OAuth-based social login through plugins. Adding Google Sign-In, for example, lets users authenticate with their existing Google account instead of creating a new password. This reduces friction at sign-up and increases conversion rates significantly.

Social login is increasingly expected by users and straightforward to implement in Bubble.

• Google OAuth plugin: Install the Google OAuth plugin and configure it with a client ID from Google's developer console to enable Google Sign-In.
• Facebook login: A similar plugin exists for Facebook authentication, following the same OAuth setup pattern.
• Linked to Bubble User: Social login creates a standard Bubble User record, which works exactly like an email-registered account.

Offering at least one social login option alongside email login gives users flexibility and typically improves sign-up rates.
