You try to sign in using your usual email and password, but the platform refuses the login.
The system may redirect you to a company login page, or display a message saying that single sign-on authentication is required.
When this happens inside a company workspace, the reason is often a new SSO policy applied by the organization administrator.
What Happens When A Workspace Enables SSO
Many enterprise platforms allow organizations to enforce single sign-on authentication.
This means users must log in through the company identity provider instead of using the normal platform login.
- company identity provider authentication
- corporate directory login verification
- centralized security control
- organization-wide login enforcement
Once this policy is enabled, standard email login may stop working completely.
Why Access Can Stop Suddenly
SSO policies are usually activated by administrators to improve security and centralized access management.
When the organization enables SSO enforcement, the platform immediately requires all users to authenticate through the company login system.
This is why users may suddenly lose access even though their accounts still exist.
How To Fix SSO Login Problems
If login fails after an SSO policy change, try accessing the platform through the company SSO login page.
- use the official company login portal
- confirm your corporate email account is active
- check whether your organization requires SSO authentication
If the workspace now requires SSO, logging in through the company identity provider should restore access.
