TL;DR: Codex users now face a higher identity-security bar because OpenAI’s Advanced Account Security disables passwords and legacy MFA, shortens session windows, and requires phishing-resistant passkeys or hardware keys for its most privileged users, according to Yubico. The practical issue is that AI-assisted coding moves ChatGPT accounts into high-consequence control points where recovery, session integrity, and developer identity governance all matter at once.
NHIMG editorial — based on content published by Yubico: OpenAI Codex account security and Advanced Account Security guidance
By the numbers:
- 70% of organisations grant AI systems more access than they would give a human employee performing the exact same job.
- Only 44% of organisations have implemented any policies to manage their AI agents, despite 92% agreeing that governing AI agents is critical to enterprise security.
- Systems with least-privileged AI access had a 17% incident rate vs 76% for over-privileged systems.
Questions worth separating out
Q: How should security teams govern AI agents that can reset accounts or change credentials?
A: They should treat the agent as a request origin, not an authorization authority.
Q: Why do AI-assisted development workflows need stronger identity controls than normal SaaS apps?
A: Because the account can authorise real execution, not just access content.
Q: What breaks when session security is weaker than login security for AI tools?
A: A strong login no longer protects the workflow once a valid session token is stolen or inherited.
Practitioner guidance
- Classify AI-assisted developer accounts as privileged identities Map every account that can access repositories, run commands, or open pull requests into privileged access governance so the workflow gets higher assurance than standard collaboration accounts.
- Require phishing-resistant authentication for code-bearing AI workflows Use hardware-backed passkeys or security keys for any account that can change source code, trigger builds, or interact with sensitive development environments.
- Shorten session lifetime for AI execution contexts Reduce the window in which a stolen token remains useful and re-authenticate before high-risk actions such as code changes, environment access, or approval submission.

AI-assisted development turns the developer account into a privileged execution identity. Once an AI system can read repositories, write code, run commands, and open pull requests, the account protecting that workflow is no longer ordinary user access. It sits inside the software delivery chain and can affect production outcomes. Practitioners should treat these identities as high-consequence access paths and govern them accordingly.
A few things that frame the scale:
- 70% of organisations grant AI systems more access than they would give a human employee performing the exact same job, according to The 2026 Infrastructure Identity Survey.
- 67% of organisations still rely heavily on static credentials despite the risks they pose to agentic AI deployments, according to The 2026 Infrastructure Identity Survey.
A question worth separating out:
Q: What should organisations do when their AI accounts rely on password reset or SMS recovery?
A: Remove those recovery paths for high-consequence accounts and replace them with stronger, device-bound recovery methods. Recovery is often the bypass route when phishing-resistant login is in place, so help-desk procedures must be designed to resist social engineering, not just support convenience.
