# Authentication

> How members sign in to to11 with a supported identity provider.

This page is about how the people in your organization sign in. For programmatic access, see [API keys](/docs/platform/api-keys).

## Signing in

Members sign in with an identity provider rather than a to11-specific password — there's no separate password to manage or reset. The supported providers are **GitHub**, **Google**, and **Microsoft**. Once signed in, what a member can do is governed by their [role and permissions](/docs/platform/roles-and-permissions).

## Single sign-on

Single sign-on is coming soon. For now, members sign in with one of the supported identity providers above. Enterprise SSO — authenticating through your organization's own identity provider — is on the way.

## Joining via invitation

A member invited to the organization completes sign-in the first time they accept their invitation. They're matched to the invitation by **verified email**: signing in with an account whose verified email matches the invited address accepts it. The first time someone signs in, any pending invitations matching their verified email are accepted automatically, and their to11 account is created from their provider profile. See [Team](/docs/platform/team).
