1Password has expanded its collaboration with OpenAI to secure credential access for Codex coding agents. The new 1Password Environments MCP Server for Codex allows developers to grant secure, just-in-time access to credentials directly within their coding workflows without exposing secrets.
As coding agents like Codex take on larger roles in software development, secure and controlled access to credentials for databases, APIs, and deployment pipelines has become essential.
Traditional methods of managing credentials — such as copying them into files, prompts, or hardcoding them — create significant security risks. The new integration addresses these challenges by ensuring secrets never leave the 1Password vault.
Developers can prompt Codex to use the 1Password MCP server to retrieve and apply credentials. Secrets are injected only at runtime into authorized processes and are available only for the duration of the session or execution.
- Catch secrets at the source by having Codex store and use credentials through 1Password. - Use secrets without seeing them, allowing references inside Codex without exposing values in code or terminals. - Keep secrets outside of code by replacing hardcoded credentials with vaulted references.
“As coding agents take on more of the software development lifecycle, the question isn't whether to give them access, but how,” said Nancy Wang, CTO of 1Password. “A credential that persists is already compromised. That’s why just-in-time credentials are the only viable security model for AI-native development.”
“As developers bring coding agents into real software workflows, secure access to credentials is critical,” said Nick Steele, Agent Security at OpenAI. “1Password's MCP server for Codex helps teams give agents the access they need at runtime, without copying credentials into prompts, local files, or repositories. That’s the kind of security that simplifies agentic development, empowering teams to ship faster while keeping sensitive credentials protected.”
This integration advances 1Password’s Unified Access platform, providing a single source of truth for governing access for both humans and AI agents.
