When Does Your B2B SaaS Need Single Sign-On?
What SSO is, why larger customers ask for it, and how to add it without disrupting existing users.
Single sign-on (SSO) lets employees log in to your product using their company account, managed by their organisation's identity provider. For B2B SaaS products, SSO requests usually arrive when you start selling to larger companies.
Why customers want SSO
- Security: the company controls passwords, multi-factor authentication, and access policies centrally.
- Convenience: employees use one login for many tools.
- Control: when someone leaves, their access to every tool can be removed at once.
When to add it
- Customers in larger organisations or regulated industries start asking for it.
- Security questionnaires list it as a requirement.
- Deals are delayed or lost without it.
For most early-stage products, it can wait until there is real demand.
What implementing SSO involves
- Supporting common standards so customers can connect their identity providers
- Letting each customer organisation configure its own SSO settings
- Matching users to existing accounts safely
- Deciding whether SSO is optional or enforced for an organisation
- Optionally, automated user provisioning so accounts are created and removed automatically
Avoid disrupting existing users
Introduce SSO per organisation, allow admins to test it before enforcing it, and keep a secure recovery path for account owners in case of misconfiguration.
Plan and pricing
Many SaaS products include SSO in higher-tier plans because it is primarily valuable to larger customers.
Design authentication so SSO can be added without rewriting how users and organisations work.
MOKRIN builds authentication that is ready for SSO, so when larger customers ask for it, you can say yes quickly.
