OpenAI has introduced a new security-focused feature for ChatGPT called Lockdown Mode, designed to help reduce the risk of data theft and protect users from prompt injection attacks. The optional setting is now rolling out to eligible ChatGPT users and business accounts, offering an additional layer of protection when working with sensitive information.
According to OpenAI, Lockdown Mode focuses on preventing unauthorized data transfers by limiting internet-connected features that could potentially be exploited by attackers.
What Is ChatGPT Lockdown Mode?
Lockdown Mode is a new security setting that restricts certain ChatGPT capabilities involving web access, external services, and live integrations.
The feature is designed to reduce the chances of sensitive information being exposed if malicious content attempts to manipulate the AI’s behavior.
While Lockdown Mode does not stop harmful prompts from appearing in documents, websites, or files processed by ChatGPT, it aims to block one of the most important stages of an attack — the unauthorized transfer of data.
Understanding Prompt Injection Attacks
Prompt injection attacks occur when hidden instructions are embedded inside content that an AI system processes.
These instructions may be concealed in:
- Web pages
- Documents
- PDFs
- Uploaded files
- Online content
If successful, they can influence how an AI model responds and potentially trick it into revealing information that should remain private.
As AI tools become more connected to external services and data sources, protecting against these threats is becoming increasingly important.
What Changes When Lockdown Mode Is Enabled?
When users activate Lockdown Mode, ChatGPT restricts several features that rely on internet access or external connections.
Some of the biggest changes include:
- Live web browsing becomes limited
- Deep Research is disabled
- Agent Mode becomes unavailable
- File downloads for analysis are blocked
- Certain external integrations stop working
Users can still manually upload files, but ChatGPT loses the ability to retrieve external files on its own.
OpenAI notes that search results may sometimes be less complete or less up to date while Lockdown Mode is active.
Restrictions on Apps and External Integrations
Lockdown Mode also affects how ChatGPT interacts with connected apps and services.
The feature blocks:
- Live connector access
- External write actions
- Shopping agent functionality
- Financial service integrations
However, some synchronized experiences may continue working for personal users and supported business accounts without requiring live access to external services.
The goal is to reduce potential pathways that could be used to move data outside the ChatGPT environment.
Features That Continue to Work
Despite the added restrictions, many popular ChatGPT features remain available.
Lockdown Mode does not affect:
- Memory
- Shared conversations
- Image generation
- Chat history
- AI model improvement settings
OpenAI also states that network access within Codex remains unchanged.
Another important limitation is that Lockdown Mode cannot be enabled at the same time as Developer Mode. Activating one option automatically disables the other.
How to Enable Lockdown Mode in ChatGPT
Eligible users can turn on Lockdown Mode directly from the ChatGPT settings menu.
Follow These Steps:
- Open ChatGPT
- Go to Settings
- Select Security
- Open Advanced Security
- Enable Lockdown Mode
Once activated, ChatGPT will automatically apply the additional security restrictions.
Who Can Use Lockdown Mode?
OpenAI says Lockdown Mode is being made available to multiple account types.
Eligible users include:
- Free accounts
- Go subscribers
- Plus subscribers
- Pro subscribers
- Self-serve ChatGPT Business accounts
The feature is expected to become available gradually as the rollout continues.
Why It Matters
As AI assistants gain access to more tools, apps, and external services, security concerns continue to grow. Prompt injection attacks have become one of the most discussed risks in AI safety because they can potentially manipulate how AI systems behave.
By limiting outbound connections and reducing access to external services, Lockdown Mode provides users with an additional security option when handling sensitive information.
For businesses, researchers, and privacy-conscious users, the feature could help lower the risk of accidental data exposure.
Final Thoughts
OpenAI’s new Lockdown Mode represents another step toward improving AI security and user privacy. Rather than attempting to block every prompt injection attack, the feature focuses on preventing attackers from extracting valuable information through external connections and integrations.
Although enabling Lockdown Mode comes with certain feature restrictions, users who prioritize security may find the trade-off worthwhile. As AI tools continue to evolve, features like Lockdown Mode could play an increasingly important role in protecting personal and business data.
