With the Slack + Auth0 integration, you can add the option for your users to sign in to your application with their existing Slack account. This can greatly improve user onboarding by allowing users to skip the email and password creation step. The integration also allows pulls some basic profile information from Slack that you can use in your application.

Slack provides extensive security options to protect user accounts. Some features include multi-factor authentication, macOS Keychain access, and account logs for monitoring suspicious activity.
With over 12 million daily users, there's a good chance some of your potential users already have a Slack account that they can use to sign in to your application.
The Slack social connection allows users to log in to your application using their Slack profile.
