Do I need to switch from custom auth to SSO support?

Not necessarily. You should switch to SSO if it solves a real need, not just because it exists.

You likely should move to SSO if:

• Your users are mostly in larger companies
• They already expect Okta, Azure AD, Google Workspace, etc.
• You need centralized access control and easier offboarding
• You’re selling to enterprises and it’s becoming a sales requirement
• You want to reduce password-related support and security risk

Custom auth may still be fine if:

• You’re serving small teams or consumers
• Your product is self-serve and login simplicity matters
• Your users don’t ask for enterprise identity features
• You don’t want the added complexity of:
  • SAML/OIDC integrations
  • account linking
  • provisioning/deprovisioning
  • edge cases around email domains and multiple IdPs

A common approach

Keep custom auth for the core product, and add SSO as an enterprise feature. That gives you:

• low-friction signup/login for everyone
• SSO for customers who need it
• a path to enterprise upsell

Rule of thumb

If more than a few of your target customers are asking, “Do you support SSO?” and saying they need it to buy, it’s time to add it.

If you want, I can help you decide based on your product type, customer size, and current auth setup.
