Create ID, Sign-in, and Identity Profile Pages ## Redirect Options Once a user authenticates with the **Identity app**, the Identity app redirects the user to the accompanying User Profile. However, an organization can change the post-authentication redirect location to the authenticated view of any service or application. An organization's employees can configure the redirect URL using the Digital Identity Management**Admin console**. ## Responsive Design The **Identity app** uses a responsive design to ensure a consistent, clean layout regardless of the platform (for example, desktop or mobile view) or screen resolution. Responsive views of the Identity app on desktop and mobile browsers ## Theming and Branding Identity app supports light theme, so you can appropriately brand your public-facing sign-up and sign-in screens. Organizations can update their Identity app layout with alternate colors, fonts, and logos. If you decide to use a proprietary application and your own sign-in portal, then your developers can implement Digital Identity Management APIs and Processes into your own existing application to leverage Digital Identity Management's capabilities and enable your users to sign up, sign in, and manage their identity and services. Different themes and branding of the Identity app ## Key User Capabilities * Onboard or sign up with email address, mobile number, or social media account. * Sign in with email address, mobile number, or social media account. * Reset password if the current password is lost. * Receive verification emails and SMS to verify new or updated email addresses or mobile numbers. ## Application Settings If you want to limit the number of email addresses or mobile numbers a user can have on their User ID, enable or disable aliases, or set a list of banned passwords, then Digital Identity Management includes a suite of configurable application settings that enable you to easily define or change such limitations without the need to pause the service. * **[Identity App Errors for One-Time Password](../topics/otpIdentityAppErrorReporting_r)** **Parent topic:**[Product User Interfaces](../topics/userInterfaces) This documentation is built and hosted on [Mintlify](https://mintlify.com), a developer documentation platform.
