# Channels

> Connect the social accounts you publish to.

A **channel** is one connected social account. Postbase publishes to the
channels you select in the composer.

## Supported platforms

| Platform  | Notes                                                                     |

## Connecting an account

1. Open **Channels**.
2. Pick a platform and choose **Connect**.
3. Authorize Postbase on the provider. Postbase only requests permission to
   publish — nothing else.

<Note>
  When you connect an account, Postbase captures its display name, avatar, and
  verified status so previews look like the real thing.
</Note>

## Managing channels

Connected accounts show under **Connected**, with the account's avatar, handle,
and status. Use **Add another** to connect a second account on the same
platform, or **Disconnect** to remove one.

Your plan sets how many channels you can connect — see [Plans](/cloud/plans).
