# Codex ChatGPT Login vs API Key: quale accesso scegliere nel 2026?

Nel 2026 l'accesso a Codex non è più una semplice scelta app contro API. OpenAI supporta login ChatGPT e API key per CLI/IDE, mentre Codex cloud richiede il login ChatGPT. La release 0.136.0 aggiunge registrazione CODEX_API_KEY per host remoti approvati e server token a breve durata.

## Comparison Factors

| Factor | Codex App (ChatGPT Login) | Codex App (API Key) | Winner |
|--------|------|------|--------|
| Setup and onboarding | Browser-based login tied to a ChatGPT user or workspace; fastest path for humans. | Requires API organization access, key creation, environment/secret handling and policy setup. | a |
| Governance and data policy | Follows ChatGPT workspace permissions, RBAC, retention and residency settings. | Follows API organization retention, data-sharing and key-management controls. | tie |
| Automation and CI/CD | Best for interactive CLI, IDE and cloud sessions started by a human. | Best for scripts, CI jobs, service accounts and server-controlled agent workflows. | b |
| Codex cloud access | Required for Codex cloud according to OpenAI's authentication docs. | Works for CLI and IDE extension, but not as the primary Codex cloud sign-in path. | a |
| Remote execution security | Convenient for local users, but ChatGPT access tokens should not be reused as remote-control credentials. | Codex 0.136.0 adds CODEX_API_KEY remote registration and short-lived server tokens for approved hosts. | b |
| Credential leakage risk | Cached ChatGPT sessions can still expose powerful refresh/access tokens if auth.json is stored as a file. | API keys are easy to automate but easy to leak; they must be scoped, rotated and stored outside repos. | tie |
| Cost model | Predictable seat/subscription economics for individual and workspace usage. | Usage-based billing gives better attribution for agents, CI and high-volume jobs. | tie |
| Incident response | Disable users, enforce workspace login methods and reset sessions centrally. | Rotate keys, isolate per-agent credentials and revoke compromised automation paths quickly. | b |

## Key Statistics

- 2 supported OpenAI sign-in methods: ChatGPT login and API key
- Codex cloud requires ChatGPT login; CLI and IDE extension support both methods
- 0.136.0 published 2026-06-01 with CODEX_API_KEY remote registration and short-lived server tokens
- file-based credential storage writes access tokens to ~/.codex/auth.json under CODEX_HOME
- @openai/codex latest version: 0.136.0
- codexui-android token-exfiltration campaign affected a package with 29,000+ weekly downloads and linked Android apps with 50,000+ and 10,000+ downloads

## Choose Codex App (ChatGPT Login) When

- Ti serve Codex cloud.
- Gli sviluppatori lavorano in modo interattivo.
- Contano RBAC, retention o residency del workspace ChatGPT.
- Vuoi onboarding senza provisioning di API key.
- Puoi imporre keyring o credential store gestiti.

## Choose Codex App (API Key) When

- Codex gira in CI, script o backend.
- Vuoi attribuire i costi per agente.
- Gli host remoti usano CODEX_API_KEY e server token brevi.
- La sicurezza richiede rotazione, scope e isolamento.
- Il workflow è automation-first.

## Verdict

Usa ChatGPT login per sviluppatori umani, Codex cloud e team che vogliono controlli di workspace ChatGPT. Usa API key per automazione, CI, host remoti gestiti e attribuzione dei costi. Il pattern enterprise è ibrido: ChatGPT per le persone, API key/server token per automazione controllata e nessun ~/.codex/auth.json non gestito.

## FAQ

**Q: Meglio ChatGPT login o API key per Codex?**
A: Per gli sviluppatori umani conviene partire da ChatGPT login. Le API key sono migliori per automazione, CI e agenti controllati dal backend.

**Q: Codex cloud supporta solo API key?**
A: No. La documentazione OpenAI dice che Codex cloud richiede ChatGPT login. CLI ed estensione IDE supportano entrambi i metodi.

**Q: Le API key sono più sicure?**
A: Non automaticamente. Sono facili da isolare per job, ma anche facili da esporre. ChatGPT login può ereditare controlli workspace, ma auth.json contiene token se si usa storage su file.

**Q: Cosa cambia con Codex 0.136.0?**
A: CODEX_API_KEY per host remoti approvati, server token brevi e hardening di /diff e WebSocket da origine browser.
