How to build user authentication in Bubble

In Bubble, user authentication is built‑in. You don’t code it manually: you use the User data type, the Sign the user up and Log the user in actions, and Bubble automatically handles password storage, sessions, and cookies. A complete setup includes signup, login, password reset, email verification (optional), and privacy rules that protect user data.

Core Steps to Implement Authentication

You always work with the default User data type. It already includes fields like Email and Password. You can add more fields later (username, profile image, etc.).

• Create a signup form with 2 Inputs: an email input and a password input.
• Add a workflow on a Signup button → Account → Sign the user up.
• Create a login form and use Account → Log the user in.
• Add a "Forgot your password?" link → Account → Send password reset email.
• For email verification, enable Send email confirmation in the action.
• Protect data using Privacy Rules, e.g., “This User can view/edit their own data only if This User is Current User”.

Signup Workflow Example

// Workflow on "Sign Up" button
Account → Sign the user up
Email = Input Email's value
Password = Input Password's value
Send email confirmation = yes

Login Workflow Example

// Workflow on "Log In" button
Account → Log the user in
Email = Input Email's value
Password = Input Password's value

Important Notes

• Bubble never exposes passwords (you can’t read them, only reset them).
• Sessions are automatic — once logged in, Current User is populated.
• Always test authentication using two browsers: one logged in, one logged out.
• Use Privacy Rules to prevent leaks. UI hiding is not security; privacy rules are.

Reset Password Flow

• Create a “password reset” page.
• Use the workflow “Send password reset email”.
• The email contains a special reset link that loads the page with a token.
• On that page, use Account → Reset user’s password.

This setup gives you secure, production‑ready authentication with Bubble’s native tools, no plugins or custom code required.
