# Claude Pro/Max Subscription

> Use your existing Claude Pro/Max subscription in EnConvo

## Overview

If you already have a Claude Pro or Max subscription, you can use your existing account directly in EnConvo without needing a separate API key.

<Note>
  This is different from using the Anthropic API. Here you use your existing Claude subscription credentials.

## Validate and Use

<Steps>
  <Step title="Check connection status">
    After OAuth login, confirm the credential shows as connected in EnConvo.
  </Step>

  <Step title="Select a subscription model">
    Pick a model from the Claude subscription provider, not the Anthropic API provider.
  </Step>

  <Step title="Re-authenticate when needed">
    If requests fail after working previously, reconnect the OAuth credential from settings.
  </Step>

  <Step title="Switch accounts when needed">
    If you use more than one Claude account, disconnect the current OAuth
    credential and connect the account you want EnConvo to use.
  </Step>
</Steps>

## Account Info And Switching

EnConvo shows the connected Claude account information when available. Use it to
confirm you are sending requests through the intended Pro or Max account before
starting long chats, agents, or workflows.

If the browser login flow opens the wrong account, cancel the connection,
switch accounts in the browser, and connect again from EnConvo settings.
