+## Authenticate to push packages
+
+Pushing packages to the Upbound Marketplace requires a robot token.
+Personal API tokens and `up login` credentials don't work for pushing.
+
+### Create a robot token
+
+1. Go to `https://accounts.upbound.io/o/<your-org>/robots` and create a robot account.
+
+2. Copy the robot's **access ID** and **token**. You can't retrieve the token again after leaving the page.
+
+3. Assign the robot to a team that has write permission on the target repository.
+   See [manage repository permissions][team-repo-permissions] for instructions.
+
+### Log in with docker
+
+Use `docker login` with the robot credentials:
+
+```shell
+docker login xpkg.upbound.io -u <robot-access-id> -p <robot-token>
+```
+
+You can run [`crossplane xpkg push`][crossplane-xpkg-push] to push packages to the Marketplace.

+:::warning
+If you have the `docker-credential-up` helper configured for `xpkg.upbound.io`, it may override the robot credentials. Remove or scope it if you encounter auth errors after a successful `docker login`.
