What Does Identity Provider Actually Mean?

An Identity Provider (IdP) is a trusted authentication service that verifies users’ identities and allows them to access multiple protected applications or resources through a single set of credentials. This approach supports single sign-on, reducing the need to repeatedly enter usernames and passwords for services such as email, HR systems, and project management tools, often through standards like SAML. IdPs can also strengthen account protection with multi-factor authentication, using factors such as passwords, security tokens, fingerprints, or facial recognition. Common IdPs include Google, Facebook, Microsoft, LinkedIn, Okta, Rippling, JumpCloud, and Azure AD, while platforms such as PropelAuth offer integrations with both consumer-facing and workforce identity providers.
