 You can customize your customer's sign-in and sign-up experience in the External ID for customers tenant. Follow the guide that will help you set up the tenant in three easy steps. First you must specify how would you like your customer to sign in. At this step you can choose between two options: **Email and password** or **Email and one-time passcode**. You can configure social accounts later, which would allow your customers to sign in using their [Google](how-to-google-federation-customers.md) or [Facebook](how-to-facebook-federation-customers.md) account. You can also [define custom attributes](how-to-define-custom-attributes.md) to collect from the user during sign-up.
 
 If you prefer, you can add your company logo, change the background color or adjust the sign-in layout. These optional changes will apply to the look and feel of all your apps in this tenant with customer configurations. After you have the created tenant, additional branding options are available. You can [customize the default branding](how-to-customize-branding-customers.md) and [add languages](how-to-customize-languages-customers.md). Once you're finished with the customization, select **Continue**.
