Talent App Store allows you to control security and access to your HR eco-system. By installing identity apps, you give users the ability to sign-in securely using popular social networks and authentication services. Identity apps can be set up on a per-user type. This means that your employees can use one set of sign-in options while your candidates use another. The choice is yours. Install the Slack identity app to allow users to sign-in using an existing Slack account.
