For ChatGPT on the web, type chatgpt.com into your browser’s address bar and check the complete hostname before signing in. For a mobile or desktop app, start from OpenAI’s own download links and confirm the app-store publisher is OpenAI. A familiar logo or the word “ChatGPT” in a page or app name is not enough to verify authenticity.
Verify the website before signing in
- Open a fresh browser tab and type chatgpt.com into the address bar.
- Before entering your login details, inspect the full hostname shown in the address bar. It should be chatgpt.com; a different hostname that merely includes “ChatGPT” is not the same check.
- Do not rely on a page logo or a search-result snippet. OpenAI identifies openai.com as its company website and help.openai.com as its support site; the ChatGPT service page is at chatgpt.com.
Find the official app for your device
Use OpenAI’s Help Center app instructions as the starting point. If you search an app store yourself, check the publisher before installing. Store availability and requirements can vary by country and device, so use the current official listing for your situation.
| Device | Safer route | What to verify |
|---|---|---|
| iPhone or iPad | Open the iOS app guidance and follow its App Store link. If searching manually, use “openai chatgpt.” | The App Store publisher is OpenAI. |
| Android | Open the Android app guidance and follow its Google Play link. If searching manually, use “openai chatgpt.” | The Google Play publisher is OpenAI. |
| Mac or Windows | Start from the app links on OpenAI’s communications-verification page. OpenAI’s Windows app guidance points to the Microsoft Store. | Follow a download route linked by OpenAI rather than an unfamiliar download page. |
Be careful with social-media support messages
Do not give account details to someone who contacts you through social media claiming to provide support. OpenAI’s Help Center says: “Never share your account login details over social media.” It also says not to engage with accounts asking for account details or offering account help. Instead, navigate to OpenAI Help Center independently.
OpenAI publishes a list of its websites, social accounts, and customer email domains on its communications-verification page. That list can help you check a communication, but a listed email domain alone does not prove an unexpected message is legitimate.
