Need help with technical details before setting up Auth0 in reactjs

So we are migrating form aws cognito to auth0, I have figured out a way to migrate all the users but I need some details before i can continue, I tried contacting the sales representative but they couldn’t answer the technical questions.

  1. We have multiple environments for our application ( dev, qa, prod ) how can we seperate these user bases in auth0, by tenant or is there any other solution as well. Either way can anyone guide me on how to set these up.
  2. Do we need to use the universal login screen or is there a way we use the existing login UI we already have built into our app.
  3. If we have to use the universal login screen how can i update its domain and the url it displays on top “Sign into xyz.com” to the url for our application.
    how do we do magic links ( reset password, one time login)
  4. Social logins implementation ( Is there any additional work required from entering keys an domain with google and microsoft accounts or will it just work if i add the keys )
  5. how to setup MFA/2FA, a guide to that if it exists and how it works with the universal login if that is the only way.
  6. How can we implement account switching quickly if a user wants to switch between two or three accounts quickly ( multiple account logged in, token storage easy switching ).

Thanks for anyone who can answer.

Sure, I can help with that! Here’s a detailed guide to address your questions about migrating from AWS Cognito to Auth0 and setting up various features:

1. Separating User Bases for Different Environments

To separate user bases for different environments (dev, QA, prod), you can create multiple tenants in Auth0. Each tenant can represent a different environment, ensuring isolation between them¹⁷. Here’s how you can set it up: dollartreecompass

  • Create a new tenant for each environment: Go to the Auth0 Dashboard, navigate to the “Create Tenant” section, and set up tenants for dev, QA, and prod.
  • Assign Environment Tags: Tag each tenant appropriately (Development, Staging, Production) to manage them effectively.

2. Using Existing Login UI vs. Universal Login

You have two options for the login UI:

  • Use Existing Login UI: You can use Auth0’s Authentication API to integrate your existing login UI with Auth0. This allows you to maintain your current UI while leveraging Auth0 for authentication.
  • Universal Login: If you choose to use Auth0’s Universal Login, you can customize it extensively to match your branding. This includes updating the domain and the URL displayed.

3. Customizing Universal Login Screen

To customize the Universal Login screen:

  • Update Domain and URL: You can set up a custom domain in the Auth0 Dashboard under “Branding” > “Custom Domains”. This will allow you to use your own domain for the login screen.
  • Customize Text and Appearance: Use the Universal Login editor in the Auth0 Dashboard to change the text and appearance, including the “Sign into xyz.com” message.

4. Implementing Magic Links

Magic links can be used for passwordless authentication, reset passwords, and one-time logins:

  • Set Up Magic Links: In the Auth0 Dashboard, go to “Authentication” > “Passwordless” and enable the Email option. Configure the email template and settings as needed.
  • Limitations: Note that magic links are not supported for Universal Login but can be implemented with Classic Login.

5. Social Logins Implementation

To implement social logins:

  • Enable Social Connections: In the Auth0 Dashboard, navigate to “Connections” > “Social” and enable the desired social providers (e.g., Google, Microsoft). You will need to enter the client ID and secret for each provider.
  • Configuration: Once enabled, configure the permissions and attributes you want to retrieve from the social providers.

6. Setting Up MFA/2FA

To set up Multi-Factor Authentication (MFA):

  • Enable MFA: Go to “Dashboard” > “Security” > “Multi-factor Auth” and enable the desired factors (e.g., OTP, push notifications).
  • Customize MFA Flow: You can use Auth0 Actions to customize when and how MFA is triggered.

7. Implementing Account Switching

For account switching:

  • Account Linking: Auth0 supports linking multiple user accounts from different identity providers. This allows users to switch between accounts seamlessly.
  • Custom Implementation: You might need to implement custom logic to handle multiple sessions and token storage for quick switching.

I hope this helps! If you have any more questions or need further assistance, feel free to ask.
