Introducing Sign in with Slack
Today, we’re introducing Sign in with Slack, a way for customers to quickly sign up for your app using their Slack identity. More than just log in, Sign in with Slack keeps teams connected across the many apps they use for work.
When a user signs up for your app using Sign in with Slack, they’ll be instantly connected to their teammates within your product. For customers, this is an invisible but delightful feature. It exemplifies our mission in action — making people’s working lives simpler, more pleasant, and more productive — by keeping teams effortlessly in sync.
With Sign in with Slack, you can whitelist an entire Slack team as a group of new users, which eases billing and IT administration and improves end-user experience. On top of that, Sign in with Slack has some other handy advantages:
- It’s fast: sign up users for your app quickly by allowing them to use their existing Slack login and profile information.
- It’s simple: add sign in with Slack in 3 steps. Enrich your app experience with Slack team and user information.
- It’s secure: we’ll handle managing SSO providers and two-factor authentication, you just implement standard OAuth.
How to Use Sign in with Slack
Integrating Sign in with Slack with your app should feel familiar because it uses OAuth 2.0, just like the rest of the Slack platform. We’ve created a new set of OAuth scopes that let you choose which bits of user and team information are needed to sign in to your app.
- identity.basic: request access to basic identifying information about the user and their team
- identity.email: request access to the user’s email address
- identity.avatar: request access to the user’s profile image
- identity.team: request access to the user’s team name, domain, and icon image
Once someone’s completed the OAuth flow, all you need to do is call the users.identity method, and you’ll get all of the bits you requested for that team and user.

Upon signing in with Slack you are automatically connected to your Slack team within Quip. No extra team creation required — your team already exists within Quip in one fell swoop. From there, you can use Slack and Quip to supercharge the way that you brainstorm and create documents with your team.
The team at Figma also uses Sign in with Slack to onboard new customers and connect them with their teammates within Figma.
