SSO (single sign-on) lets a user log into a DAM using the identity they already have with their organization — the same login that gets them into email or their laptop — instead of a separate username and password created just for that one tool.
In plain English
Without SSO, every tool a team uses needs its own account: its own password, its own reset flow, its own place where a departing employee's access has to be manually revoked. SSO connects the DAM to a central identity provider (common examples are Okta, Microsoft Entra ID, or Google Workspace) so that logging in is really just proving you're already signed into that central system. The DAM trusts the identity provider's word for who you are, using a standard protocol (commonly SAML or OIDC) to check.
The practical benefit isn't really convenience, though one password to remember is nice — it's control. When someone leaves the organization or changes role, disabling their account in the central identity provider is enough; there's no separate DAM password sitting around that IT forgot to revoke. That single point of control is exactly what security reviews and compliance audits are checking for.
SSO handles authentication (proving who you are). It's commonly paired with, but distinct from, SCIM provisioning, which automates account lifecycle — creating, updating and removing DAM accounts automatically as people join, move, or leave in the identity provider, rather than an admin doing it by hand for every single tool.
Why it matters in a DAM
SSO support is rarely the deciding factor for a small team evaluating a DAM, but it's often a hard requirement once an organization crosses a certain size or works with any regulated industry — IT security policy may simply prohibit standalone tool passwords entirely. Checking for real SSO support (not just "we support SSO" in marketing copy, but a documented, working SAML/OIDC integration) is worth doing early if your organization already has that requirement, since it can silently rule out otherwise-good tools.
Buyer’s test: if your organization requires SSO, ask during a trial whether it's included on the plan tier you're actually evaluating — SSO is frequently gated behind the top enterprise tier specifically, not available on a mid-tier plan even if the vendor's homepage lists it as a feature.

FAQ
What does SSO mean for DAM software?
SSO (single sign-on) lets people log into the DAM with the credentials they already use for their organization's identity provider - Okta, Microsoft Entra, Google Workspace - instead of a separate username and password created just for that tool. One login, centrally controlled. For users it removes a password to forget; for the organization it means the DAM obeys the same authentication rules as everything else, including multi-factor requirements and whatever happens when an account is disabled.
Is SSO the same thing as SCIM provisioning?
No, they solve related but different problems, and buying one while assuming you got the other is a common mistake. SSO handles logging in. SCIM provisioning automatically creates, updates and removes user accounts in the DAM whenever someone joins, changes role or leaves in the identity provider. Without SCIM, an admin still creates each account by hand and has to remember to remove it - even if the login itself goes through SSO.
What are SAML and OIDC?
The two protocols SSO is normally built on. SAML is the older, XML-based standard and is still what most enterprise identity providers and DAM tools speak. OIDC (OpenID Connect) is the newer, JSON-based one built on OAuth 2.0, and is common where the login is more consumer-facing or mobile. Functionally, either can deliver what you want. What matters is that the DAM supports whichever your identity provider already runs, so ask for the specific protocol rather than a checkbox saying 'SSO'.
Does SSO replace permissions in a DAM?
No. SSO answers who someone is; role-based access control answers what they may do once inside. Turning on SSO does not decide whether a new arrival can delete a collection - that is still the DAM's own permission model, and it still has to be configured. The two connect through provisioning: in good setups a directory group maps onto a DAM role, so identity and authorization stay in step. Without that mapping, SSO just makes the front door convenient.
Is SSO usually an extra cost?
Often, yes - many vendors keep SSO behind a higher plan or an add-on rather than including it in entry tiers, so it is worth pricing explicitly rather than assuming it comes with the seats. If SSO is a security requirement for your organization, treat it as a hard filter early in the shortlist, because discovering at contract stage that it forces a plan jump changes the comparison entirely. Ask about SCIM in the same conversation; it is often gated the same way.
