Overview

Implementing passwordless login in Adalo makes user authentication easier by letting users access their accounts without a traditional password. Instead, users receive secure, single-use login links or codes via email or other methods. Adalo doesn’t have built-in support for passwordless authentication, but you can integrate third-party services or use custom actions and APIs to create a smooth passwordless login experience for your app's users. This approach can enhance security and offer greater convenience for users.

How to implement passwordless login in Adalo?

Step 1: Set Up Your App

First things first, create a new Adalo app if you haven't already. Head over to your Adalo dashboard and pick the type of app you want to build, whether it's a native mobile app or a web app. Easy peasy.

Step 2: Add the User Collection

Make sure your Adalo app has a user collection. Usually, Adalo apps come with this pre-made. The user collection should have fields like email and any other info you might need. Simple, right?

Step 3: Create the Passwordless Login Screen

Create a new screen in your Adalo app for passwordless login. You can call it "Passwordless Login." Straightforward, isn't it?

Step 4: Add an Input Field for Email

On the "Passwordless Login" screen, add a text input field where users can type in their email addresses. Label it clearly.

Step 5: Add a Button to Submit the Email

Add a button right below the email input field. Label it "Send Login Link" or something similar.

Step 6: Create an Action for the Button

Set an action for the "Send Login Link" button. This action should trigger a custom action to send a magic link to the user's email.

Step 7: Create the Magic Link Screen

Create another screen in your app for users to land on after clicking the magic link. You can name this screen "Magic Link Verification."

Step 8: Set Up a Workflow for Sending Emails

Create a new workflow that sends an email with a unique URL containing a token to the user's email address.

To do this:

  • Use an external emailing service like SendGrid, Mailchimp, or something similar.
  • The URL should direct the user to the "Magic Link Verification" screen and include a unique token as a URL parameter.

Step 9: Generate and Store Tokens

Generate a unique token for each login request. Save this token in a new collection (e.g., "Login Tokens") that associates it with the user's email.

Step 10: Verify the Token

On the "Magic Link Verification" screen, set an action that checks the URL parameter to verify the token. Match this token with the token stored in the "Login Tokens" collection.

Step 11: Handle Successful Verification

If the token is valid, log the user into the app by setting them as the logged-in user. You can redirect them to the home screen or any other appropriate screen after successful login.

Step 12: Set Token Validity Period

Optionally, set an expiration time for the tokens to enhance security. This can be done by adding a timestamp to the "Login Tokens" collection and checking it during verification.

Step 13: Clean Up Tokens

Implement a cleanup mechanism to delete expired or used tokens from the "Login Tokens" collection to keep your database clean.

By following these steps, passwordless login can be successfully implemented in an Adalo app.
