### What You Need

Before logging in to the mobile app, you need your company domain (tenant domain). This ensures you access the correct organization workspace.

### Finding Your Company Domain

Your company domain can be found in:

1. Invitation Email: When your administrator invited you, the email included your unique domain URL (e.g., [companyname.kb.theblockbrain.ai](http://companyname.kb.theblockbrain.ai))\ <br>
2. Web Browser URL: If you already access Knowledge Bots via web browser:

* Open the platform in your browser
* Look at the address bar at the top of your browser
* Your domain is visible in the URL (e.g., <https://companyname.kb.theblockbrain.ai/>)

#### Step 2: Login with Credentials

1. After entering the correct domain, you'll be redirected to the login screen
2. Enter your email address
3. Enter your password
4. Tap Login

### Troubleshooting

Can't find your domain?

* Check your invitation email from <auth@theblockbrain.io>
* Contact your organization's administrator
* Look for the Email Suffix in your invitation (this is typically your domain)

💡 Note: Unlike the previous login flow, the mobile app now requires the domain first to ensure you're accessing the correct organization workspace.
