Bug Description
A clear and concise description of the bug.

Steps to Reproduce

Be unlucky 🙂

Configure OpenCode with the plugin list below

Start OpenCode

Expected Behavior
OpenCode should successfully download and load the OpenAI Codex multi-account plugin, allowing the use of multiple OpenAI Codex accounts.

Actual Behavior
The plugin is never downloaded nor loaded.

I am trying to install the plugin using the correct name in opencode.json:

{
"plugin": [
"oh-my-opencode",
"opencode-antigravity-auth@latest",
"opencode-openai-codex-auth-multi@latest"
]
}

Despite this configuration, the plugin does not appear to be installed or executed.

Environment
OpenCode version: 1.1.36
Plugin version: Not installed / not downloaded
Operating System: Windows 11
Node.js version: Not specified

Logs
No logs are available under
~/.opencode/logs/codex-plugin/

The plugin does not seem to be downloaded at all, even with ENABLE_PLUGIN_REQUEST_LOGGING=1 enabled.

Compliance Checklist

I’m using this plugin for personal development only

I have an active ChatGPT Plus/Pro subscription

This issue is not related to commercial use or any TOS violation

I have reviewed the FAQ and troubleshooting documentation

Additional Context
I tested all available versions of the plugin using both npm and bun:
4.3.0-multiaccount.1
4.3.1
4.5.0
4.6.0
4.7.0

None of these versions work.
The plugin is never downloaded or activated.

Hello @rainmeter33-jpg, thank you for the thorough report.

tl;dr: This is not a bug in this plugin. It is an upstream OpenCode issue. OpenCode blocks any plugins that contain opencode-openai-codex-auth in the name.

Current Behavior

OpenCode has this condition inside their plugin loader (source):

if (plugin.includes("opencode-openai-codex-auth") || plugin.includes("opencode-copilot-auth")) continue 

This skips loading our plugin since OpenCode comes with their own CodexAuthPlugin that authenticates with OpenAI. They want to avoid collisions I'm assuming, but it also prohibits 3rd party plugins such as ours from loading.

Summary of current behavior

• Plugin downloads successfully ✓
• Plugin is in ~/.cache/opencode/node_modules/ ✓
• Plugin never loads or executes ✗
• No logs show because it never runs ✗

What we've done

1. Documented this known limitation (see troubleshooting)
2. Created a draft upstream PR proposal (https://github.com/ndycode/opencode-chatgpt-multi-auth/blob/main/docs/OPENCODE_PR_PROPOSAL.md) to support multiple auth plugins per provider
3. Created a fork of OpenCode that works with this plugin by disabling the problematic check (this works, but you have to build from source)

Current workarounds

1. Use OpenCodes built-in single account auth - opencode auth login functions normally with no plugin installed
2. Wait for us to get an upstream fix - We will be submitting a PR to OpenCode soon
3. Use our patched version of OpenCode built from source - Advanced users only

I will leave this issue open until we get an upstream fix accepted.

✅ Fixed in v4.9.0

The plugin has been renamed and published under a new name that bypasses OpenCode's blocking:

New package: oc-chatgpt-multi-auth

Update your config

Change your ~/.config/opencode/opencode.json:

{
  "plugin": ["oc-chatgpt-multi-auth@latest"]
}

What changed

• Package renamed from opencode-openai-codex-auth-multi to oc-chatgpt-multi-auth
• This bypasses OpenCode's plugin loader check that blocks opencode-openai-codex-auth names
• All functionality remains the same

Verify it works

ENABLE_PLUGIN_REQUEST_LOGGING=1 opencode run "test" --model=openai/gpt-5.2

You should now see logs in ~/.opencode/logs/codex-plugin/

npm: https://www.npmjs.com/package/oc-chatgpt-multi-auth
