### Prerequisites

```auto
CakePHP4.0
cakephp/authentication": “2.*”
Composer 2,1.6

```

### Cake authentication plugin installation fail

I am trying to run my CakePHP4 app by Composer v2, which is now currently running by Composer v1 because Composer is recommending migration from v1 to v2 as soon as possible.

However, when I upgrade my local Composer version from v1 to v2, the installation of [cakephp/authentication](https://github.com/cakephp/authentication) fails.

I tried `composer clearcache` but it doesn’t work. What should I do?

```auto

    This most likely is due to a custom installer plugin not handling the returned Promise from the downloader

Are you sure you have `"cakephp/plugin-installer": "^1.3",` inside your composer.json aka have the version 1.3.1 of the `cakephp/plugin-installer` installed?
