Is this SSO?
Portalwith focuses on secure, low-friction access (magic links/password) for external users. For internal SSO, you keep using Notion; the portal sits in front for clients/customers.

Why custom login matters for Notion portals
Clients and customers shouldn’t see your entire workspace or raw Notion links. A custom login keeps things private, branded, and simple to access.
- •Protect internal pages while sharing curated client views
- •Stay on-brand with your logo, colors, and domain
- •Offer magic-link access so clients don’t need Notion accounts
- •Control who sees what with role-based visibility
- •Track portal engagement and keep audits clean
Set up a custom login in minutes
- Connect your Notion workspace and choose the databases to expose.
- Brand the login screen: domain, logo, typography, theme.
- Set roles (client, champion, collaborator) and gate blocks accordingly.
- Invite via magic link or password and keep your internal workspace private.
Great for agencies & CS teams
Agencies keep client deliverables private and organized. Customer success teams give champions a clean entry point for onboarding, QBRs, and support-without new tooling.
Keeps compliance happy
Limit exposure of sensitive data, reduce link sprawl, and keep an auditable trail of what’s shared. Configure visibility at the block and database level.
