What is Single Sign-On (SSO)?

Single Sign-On (SSO) is an authentication method that allows you to access multiple independent software systems, such as your 101domain account, using a single set of credentials. This approach helps consolidate password management and strengthens your organization’s security posture.

With SSO, your employees can securely access their 101domain accounts using their existing company credentials managed through your organization’s Identity Provider (IdP) and user directory, such as Microsoft or Google Workspace. This eliminates the need for separate usernames and passwords for 101domain.

101domain’s SSO functionality is built on the OpenID Connect (OIDC) protocol, which is an identity layer on top of the OAuth 2.0 framework. OIDC streamlines the process of verifying user identities and securely obtaining essential profile information, such as name and email address. For some providers, like Okta and OneLogin, this information is accessed directly from your authorization server.

By centralizing authentication through your organization’s IdP, you can enforce security policies and Multi-Factor Authentication (MFA) at the organizational level. This simplifies user management, reduces password fatigue for your employees, and eliminates the need to manage separate passwords for 101domain.
