Signing In to Amazon QuickSight Using an Identity Provider

If your organization uses an identity provider, you must first sign in through the identity provider before you use Amazon QuickSight.

An identity provider supports single sign-on (SSO) access. This type of access means you don't need to provide sign-in information to Amazon QuickSight. When you access Amazon QuickSight, you shouldn't see a sign-in screen.

If you do see a sign-in screen in this case, no credentials will work. You must sign in through your identity provider instead of on this sign-in screen. Then you can use Amazon QuickSight.
