# Single Identity Provider: Branding

Branding collateral associated with an organization is extremely valuable because using brand collateral provides users with an environment that they know and trust. Using recognized brand collateral also increases user confidence that the information they provide (for example, credentials) will be handled safely and securely. In our architecture scenarios, we provide general guidance on a number of [B2B Branding](/docs/get-started/architecture-scenarios/business-to-business/branding) topics, which we recommend reviewing alongside the guidance provided here.

## Universal Login

Branding a multi-organization environment can be more complex than in a standard environment where you only have to deal with one set of brand collateral. [Auth0 Organizations](/docs/manage-users/organizations/organizations-overview), however, leverages the [Universal Login experience](/docs/authenticate/login/auth0-universal-login/universal-login-vs-classic-login/universal-experience), which provides a number of [page templates](/docs/customize/login-pages/universal-login/customize-templates) to help simplify brand customization. Auth0 Organization configuration itself also allows you to [select basic color scheme branding](/docs/manage-users/organizations/configure-organizations/create-organizations).

### Login page

When using a [Database or Custom Database Connection](/docs/authenticate/database-connections), the Login page is used to obtain first-factor credentials for a user. You can configure the Login page using a set of [template variables](/docs/manage-users/organizations/create-first-organization) available to assist with per-organization customization.

  You can configure the Login Page to display Enterprise and Social Connections for first-factor authentication, so Login Page branding can be relevant in these cases.
</Callout>

### Password Reset page

Similar to the [Login page](#login-page), the Password Reset page can be configured in scenarios that use a Database or Custom Database Connection. For scenarios involving an Enterprise Connection or a Social Connection, password changes are handled external to Auth0 by the upstream <Tooltip tip="Identity Provider (IdP): Service that stores and manages digital identities." cta="View Glossary" href="/docs/glossary?term=Identity+Provider">Identity Provider</Tooltip> (IdP), so an Auth0 Password Reset page is never displayed.

### Multi-factor Authentication pages

<Tooltip tip="Multi-factor authentication (MFA): User authentication process that uses a factor in addition to username and password such as a code via SMS." cta="View Glossary" href="/docs/glossary?term=Multi-Factor+Authentication">Multi-Factor Authentication</Tooltip> (MFA) in Auth0 is supported for all methods used to obtain first-factor credentials for a user (i.e., Database or Custom Database Connection, Enterprise Connection, or Social Connection). If you're using MFA, then you will likely want to brand the <Tooltip tip="Universal Login: Your application redirects to Universal Login, hosted on Auth0's Authorization Server, to verify a user's identity." cta="View Glossary" href="/docs/glossary?term=Universal+Login">Universal Login</Tooltip> experience pages associated with MFA, which can be done similarly to [Login page](#login-page) branding.

## Email templates

As with Universal Login page templates, a set of [email template variables](/docs/customize/email/email-templates/supported-liquid-syntax#general-variables) are available to assist with per-organization email customization. The email templates that need to be customized will vary depending on how users are authenticated (in other words, via Database or Custom Database Connection, Enterprise Connection, or Social Connection). To learn more about email template customization when using the Auth0 Organizations feature, see [Create Your First Organization: Email Templates](/docs/manage-users/organizations/create-first-organization).

## Custom Domains

The Auth0 Organizations feature supports only one [Custom Domain](/docs/customize/custom-domains), which is defined at the Auth0 Tenant level. Therefore, we recommend that you use a <Tooltip tip="Custom Domain: Third-party domain with a specialized, or vanity, name." cta="View Glossary" href="/docs/glossary?term=Custom+Domain">Custom Domain</Tooltip> Name that is organization agnostic. If you absolutely must implement per-organization domain naming, then multiple Auth0 Tenants will need to be deployed to production. Because using multiple tenants has ramifications that affect <Tooltip tip="Single Sign-On (SSO): Service that, after a user logs into one applicaton, automatically logs that user in to other applications." cta="View Glossary" href="/docs/glossary?term=Single+Sign-On">Single Sign-On</Tooltip> (SSO), user profile management, and so on, you should carefully consider before going down this route.
