A cloud identity platform is a cloud service organizations use to manage digital identities and control access to connected applications. It can authenticate users as an identity provider (IdP), apply sign-in policies, and coordinate identity records across systems. Its key capabilities work together but do different jobs: single sign-on (SSO) handles access to configured applications, multi-factor authentication (MFA) strengthens sign-in proof, and lifecycle management creates, updates, or removes accounts as people and roles change.
What a cloud identity platform does
The platform sits between an organization’s identity sources—such as an HR system or directory—and the applications employees use. It can centralize authentication and access policy for cloud-only environments or connect to on-premises systems in a hybrid deployment. Microsoft documents both cloud-only and hybrid identity patterns in its Microsoft Entra hybrid identity guidance.
A typical flow has three distinct parts: an authoritative source records a person’s identity and status; the identity platform authenticates that person and applies policy; and connected applications either trust the platform for sign-in, receive account data through provisioning, or both. These are separate integrations, even when a provider offers them in one product.
How SSO works
Single sign-on lets a user authenticate through an identity provider and access applications configured to trust it. The user signs in with the IdP; an application then accepts the IdP’s configured sign-in assertion or response. Microsoft describes SSO as signing on once to access SSO-enabled applications.

SSO is not automatically available for every application in an organization. Each app needs a supported integration path and correct configuration. One common approach is SAML federation. For example, Google’s documented Microsoft Entra and Google Cloud Identity/Google Workspace integration uses a SAML profile and a separately configured Entra enterprise application. The guide was last reviewed March 6, 2026, and describes that specific setup, not a universal procedure.
SSO reduces the need for separate application sign-ins and gives administrators a central place to apply authentication policy. But it does not, by itself, guarantee that a user account exists in the target application or that the account will be removed when the user leaves.

What MFA adds
Multi-factor authentication requires more than one kind of proof to establish a user’s identity at sign-in. An organization chooses the methods and policies; the right balance depends on risk, usability, and what the identity provider and applications support.
Microsoft’s identity maturity guidance recommends phishing-resistant options, including FIDO2 passkeys, physical security keys, and certificate-based authentication. A FIDO2 security key is an optional physical device—not a requirement for every cloud identity platform. Check provider support, account configuration, user needs, and organizational policy before selecting one.

Lifecycle management: creating, changing, and removing accounts
Identity lifecycle management keeps accounts and access aligned as people join, change roles, or leave. Automated provisioning can create identities and roles, maintain them as status or role information changes, and remove them when appropriate. Microsoft describes these lifecycle functions in its application provisioning documentation.
Provisioning and SSO solve different problems. Provisioning supplies or updates an application account and its attributes; SSO lets a user sign in through a trusted identity provider. Google’s integration guide provisions users first and configures a separate SAML sign-in profile, illustrating why one should not be assumed to include the other.

What SCIM provisioning means
SCIM, or System for Cross-domain Identity Management, is an open standard for exchanging identity information between domains and IT systems. Microsoft describes standard /Users and /Groups endpoints, REST operations to create, update, and delete objects, and common fields such as usernames, names, email addresses, and group names. Its SCIM synchronization guidance explains how supported Microsoft Entra integrations use SCIM 2.0 to provision or deprovision users and groups.
SCIM can reduce the need for a proprietary account-management integration when both systems support it, but it is not universal plug-and-play compatibility. The target application needs a supported SCIM endpoint or connector; an administrator must supply valid authorization credentials and configure attribute mappings and provisioning scope. Some legacy systems may require an on-premises agent or connector to translate provisioning operations.

How the capabilities fit together
| Capability | What it controls | What it does not guarantee |
|---|---|---|
| SSO | Sign-in to applications configured to trust the identity provider. | That every application is connected, or that an application account is created or removed. |
| MFA | Additional authentication proof at sign-in, according to the organization’s policy. | That a user has an account in every needed application or that access is current. |
| Lifecycle management and provisioning | Creation, updates, and removal of accounts and attributes in supported systems. | That the target supports the needed connector, mappings, scope, or sign-in federation. |
In practice, a person’s identity and status originate in an authoritative system. The platform applies sign-in policy; SSO enables access to configured applications; and provisioning synchronizes the corresponding application account. When someone’s status or role changes, lifecycle rules can update or remove that account. The organization must configure both the identity connection and the application-side integration for the intended result.
What to compare when evaluating platforms
- Identity source and directory fit: Confirm whether the service works with the HR system, cloud directory, on-premises directory, or hybrid arrangement you rely on.
- Application coverage and federation: Check that the required applications have suitable connectors and support the sign-in protocols your organization needs. A published connector alone does not confirm that your required configuration is covered.
- MFA methods and policy controls: Verify support for the methods you require, especially phishing-resistant options, and confirm that policies can enforce them for the intended users and applications.
- Lifecycle automation: Check SCIM and group provisioning support, attribute mappings, scope rules, and what happens on updates and deprovisioning.
- Administration and integration: Identify required service credentials, delegated privileges, agents, mapping decisions, and who will own ongoing configuration. Google’s example calls out identity, group, and domain mappings as well as privileges for the provisioning account.
- Licensing and deployment effort: Confirm current plan requirements and whether the needed application licenses are in place. Microsoft notes that appropriate application licenses may be required and provisioning is configured per application; pricing and entitlements depend on current vendor plans.
Microsoft Learn documentation accessed October 4, 2026, describes Microsoft Entra capabilities; feature availability and licensing can vary by plan and change. Verify current vendor documentation for a specific deployment rather than assuming every platform or application supports the same protocols, connectors, or policies.
