Most SaaS platforms treat login and service connections as separate flows. Sign in with Google. Then go to Settings. Then Connect Google again. Five steps for what should be one.

Universal OAuth

When you click Continue with Google on 0nCore, we request extended scopes — Analytics, Gmail, Drive, Sheets, Calendar — in the same OAuth flow. Your sign-in IS your service connection. One click, everything wired.

The Bridge

The auth callback automatically bridges the OAuth token into a user_connections table. The same token that authenticates your session also grants API access to your services. No second flow. No settings page required.

Why This Changes Retention

The number one reason users abandon a SaaS product is setup friction. Every additional step is a 20-30% drop-off. Collapsing sign-in and service connection into one step eliminates the biggest friction point in the entire funnel.

Every Provider, Same Pattern

Google, LinkedIn, Slack, Facebook, GitHub, X — every provider follows the same architecture. One login. Every service connected. Zero configuration.
