Identity & Access

What is Single Sign-On (SSO)? — Indian Business 2026 Guide

Single Sign-On (SSO) is an authentication method where users log in once with one set of credentials and access multiple applications. Instead of separate passwords for Zoho, Slack, AWS, and email, users sign in once via an identity provider (like Google, Microsoft, or Okta) and SSO grants access to all connected apps.

SSO typically uses standards like SAML 2.0, OpenID Connect (OIDC), or OAuth 2.0. The user authenticates with the Identity Provider (IdP) — usually Microsoft Entra ID (Azure AD), Google Workspace, Okta, or OneLogin. The IdP issues a security token that Service Providers (apps like Zoho, Slack, AWS) trust. SSO improves security (one strong password + MFA instead of many weak ones), user experience (no password fatigue), and IT control (central user provisioning/deprovisioning). For Indian enterprises, SSO is mandatory above 50-100 users for security hygiene.

Frequently Asked Questions

What is the best SSO provider for Indian enterprises?

For Microsoft 365 / Azure-shop enterprises: Microsoft Entra ID (Azure AD) — free with M365 Business Premium and above. For Google Workspace customers: Google as identity provider (free with Workspace). For multi-cloud / specialist SSO: Okta (~$2-15/user/month). For simpler needs: OneLogin or JumpCloud. Most Indian enterprises use Microsoft Entra ID because they already pay for it via M365.

How much does SSO implementation cost for Indian SMBs?

If you already have Microsoft 365 Business Premium (₹1,560/user/month) or Google Workspace, SSO is included at no extra cost. Standalone SSO (Okta, OneLogin) costs ~₹200-1,500/user/month depending on features. Implementation effort: ~40-80 hours for 10-30 apps. Most Indian SMBs use the M365/Workspace bundled SSO to avoid extra license cost.

Which SaaS apps support SSO in India?

Most modern SaaS support SSO: Zoho (all products), Microsoft 365, Google Workspace, Slack, AWS, Atlassian (Jira/Confluence), Salesforce, HubSpot, Freshworks, Notion (Business plan), Asana, Monday.com. Indian-origin tools (Zoho, Freshworks, GreytHR, Razorpay) all support SAML 2.0. SSO is now a standard expectation for B2B SaaS.

Do I need MFA if I have SSO?

Yes — SSO and MFA work together. SSO consolidates passwords; MFA adds a second factor (authenticator app, hardware key, SMS). Without MFA, a stolen SSO password gives access to everything. With MFA, even a stolen password is blocked by the second factor. For Indian businesses, mandatory MFA on the SSO identity provider is non-negotiable.

How does SSO improve Indian SMB security in practice?

Three concrete benefits: (1) Faster offboarding — when employee leaves, deactivate them in IdP and they lose access to ALL apps instantly (vs manually removing from each app), (2) Stronger passwords — users have only 1 SSO password to remember, so they use stronger ones, (3) MFA everywhere — one MFA implementation covers all SSO-enabled apps, instead of MFA setup per app.
