Integrating Bitwarden with Single Sign-On

Single Sign-On delivers powerful authentication for applications that support it, but up to two-thirds of business applications fall outside SSO coverage. Legacy systems, vendor portals, personal SaaS tools and emerging applications require traditional authentication. This creates security blind spots where employees resort to weak or reused passwords.

Bitwarden complements existing SSO deployments rather than replacing them. By integrating Bitwarden for business or enterprise with your identity provider, organisations extend security policies across both SSO-enabled applications and the tools that require traditional credentials. The result is comprehensive credential security without gaps, regardless of apps’ authentication methods.

Bitwarden works with any identity provider supporting SAML 2.0 or OpenID Connect (OIDC) for logging in with SSO. This includes Microsoft Entra ID, Okta, Ping Identity, Google Workspace and other standards-compliant providers. Using an organisation’s existing SSO to log in to Bitwarden allows organisations to add complete credential coverage without having to reconfigure their set-up or switch to a different solution.

Zero-knowledge architecture

The integration preserves zero-knowledge encryption through architectural separation. Your identity provider handles authentication while Bitwarden manages credential storage and vault decryption. This split means that your encryption key is never exposed to your identity provider, and it cannot access vault data. Encryption keys remain exclusively under organisational or user control, never passing through external servers.

With authentication managed through the IdP, this design enables SSO authentication to control access to the Bitwarden vault itself, extending SSO protections to every credential stored within, even for applications that lack SSO support.

Flexible decryption approaches

With the zero-knowledge, end-to-end encrypted design, the keys used for encrypting user and organisation vaults are kept with the organisation through one of three methods. Organisations select the decryption method that matches security requirements and user experience goals.

Main password decryption: After SSO authentication, users enter their Bitwarden master password to decrypt vault contents. This maintains user-controlled encryption while leveraging SSO for authentication.

SSO with trusted devices: Registered devices store encryption keys, eliminating the need for a master password after SSO authentication. This creates a passwordless experience while preserving zero-knowledge encryption.

Key Connector: Self-hosted organisations can deploy Key Connector to manage decryption keys on infrastructure they control, maintaining zero-knowledge principles while centralising key management, so that users do not have to enter master passwords. This is an advanced option and requires significant IT resources and knowledge to implement securely.

Manual account management becomes impractical at enterprise scale. Bitwarden offers two automated provisioning options that synchronise with existing directory services.

SCIM provisioning

System for Cross-domain Identity Management (SCIM) enables real-time directory synchronisation. When IT adds employees to the directory, SCIM automatically creates Bitwarden accounts with appropriate group memberships. When employees depart, SCIM immediately revokes access. This automation closes the security gaps that manual processes create during employee transitions.

SCIM integration is available for Microsoft Entra ID, Okta, OneLogin, JumpCloud, and Ping Identity.

Directory Connector

Organisations using directory services without SCIM support can deploy Directory Connector, a standalone application that synchronises users and groups from LDAP, Active Directory, and other directory systems on a scheduled basis. This provides automated provisioning for environments where SCIM is not available.

SSO and Bitwarden together deliver comprehensive protection across different credential types.

Non-SSO applications: Bitwarden generates strong, unique passwords and stores credentials securely with the same organisational oversight as SSO, and access can be revoked through the IdP and SCIM systems.

Vendor and contractor sharing: Securely share credentials with external parties through encrypted collections with granular access controls and audit trails by temporarily inviting users who aren’t within the IdP

Enterprise policy enforcement: Require SSO authentication for non-admin users, enforce account recovery enrolment, restrict users to single organisation membership, and mandate two-step login.

Granular access controls: Role-based access controls, custom roles, and collection-based permissions support least-privilege principles across shared credentials.

Comprehensive audit trails: Event logs capture credential access, sharing, modifications, and policy changes across all users and applications.

Password policy enforcement: Generate complex passwords that meet organisational standards and identify weak, reused, or compromised credentials across all systems.

Organisations that implement SSO and Bitwarden together gain complete credential security across their application landscape. Rather than accepting security blind spots or limiting tool choices, the combination protects SSO investments by extending authentication policies to applications outside SSO coverage. This comprehensive approach eliminates weak and reused passwords across all systems while maintaining visibility into credential health organisation-wide, which significantly reduces credential-related incidents.

The integration streamlines both onboarding and succession planning. Automated provisioning ensures employees gain access quickly when they join, while synchronised deprovisioning triggers immediate credential revocation when they depart. For organisations working with external partners, the solution enables secure collaboration by allowing teams to share credentials with vendors and contractors through encrypted channels that provide granular permissions and comprehensive audit trails.

From a compliance perspective, detailed logging and reporting demonstrate comprehensive credential management across all systems, not just SSO-enabled applications. This helps organisations maintain their compliance requirements. At the same time, the solution improves the employee experience by allowing seamless credential access across devices while IT maintains centralised control and enforces consistent security standards throughout the organisation.

Organisations already using SSO can add Bitwarden without disrupting existing authentication systems. The integration works within current infrastructure to deliver unified access management that covers all applications.
