# Managing Connectors

> Configure, secure, version, and extend the connectors your projects use.

Everything that keeps your connectors running, from setting up authentication to versioning and building new ones.

<Note>
  This assumes you already have a connector profile. To create one, follow [Setup Connector Profile](/gateway/quickstart#setup-connector-profile) in the Quickstart.
</Note>

## Connector Profiles

A connector can have more than one [connector profile](/gateway/concepts/connector-profiles), with one set as default. That default is used when there is no specific connector profile supplied during the [account linking](/connect/managing-connectors/linking-accounts) process. The default can be changed on the [Connector Profiles page](https://app.stackone.com/connector_profiles).

Authentication, scopes, and the version pin all live on the profile, so a second profile is how you vary any of them for a subset of your accounts:

| Reason                                            | Example                                                                                |
| ------------------------------------------------- | -------------------------------------------------------------------------------------- |
| Two authentication methods for the same connector | An API Key profile for customers without OAuth, and an OAuth profile for everyone else |
| Different action and event scopes                 | A read-only profile for trial accounts, a full-access one for paid                     |
| A staging profile for a new connector version     | Pin one profile to `2.x.x` and test it before moving production profiles off `1.x.x`   |

Disabling a connector profile takes it out of service without deleting anything. It disappears from the Hub, and its linked accounts go `inactive` until you re-enable it. Deleting a profile is more restricted: it has to have no linked accounts, and it has to be either the connector's only profile or a non-default one.

<Warning>
  Requests against an `inactive` account are blocked, so disabling a connector profile stops live traffic for every account linked to it.
</Warning>
