To check whether a ChatGPT or other AI login page is genuine, inspect the full hostname in your browser’s address bar, then open the service independently using an address you already trust. Don’t rely on a logo, familiar design, search result, or urgent message. If you may have entered your password on a fake site, secure the real account promptly.
How do I know if a ChatGPT website is real?
Read the complete hostname in the address bar before entering a password or verification code. The hostname is the website address, including the domain ending; a service name appearing somewhere in a longer address does not prove the service provider owns it. For example, a name before another domain can be a subdomain, not the destination you intended.
OpenAI’s help guidance names chatgpt.com and openai.com as examples of trusted destinations. For login troubleshooting, it directs users to chatgpt.com/auth/login. Official domains and routes can change, so check OpenAI’s current guidance if something does not match.
- Check the address bar, not just the page. A copied logo, convincing layout, or familiar wording can be used on a site controlled by someone else.
- Compare the displayed link with its destination. A link label can conceal a different URL. CISA advises checking that the two match; if you cannot verify the destination, don’t open it.
- Be wary of pressure. An unexpected message urging you to sign in immediately or confirm account details is a reason to pause, not a reason to skip checking.
OpenAI’s account-security guidance says to “Always double-check the email address and URL to make sure they are from a trusted source.”

Is this ChatGPT login link safe?
If a link arrived unexpectedly in an email, text, or social-media message, don’t use it to sign in. Type an official address yourself or use a saved bookmark, then navigate to the account from there. Do not share your login details or verification codes through an unverified link or social-media message; OpenAI explicitly warns users not to share account login details over social media (OpenAI guidance on verifying communications).
The same caution applies to links shown in an AI conversation. A link appearing in ChatGPT is not automatically safe: OpenAI advises users to inspect generated-link destinations and notes that third parties may supply malicious links (OpenAI guidance on generated links).
If a login page gives an error or you see a suspicious-activity alert, that alone does not establish that the page is fraudulent. Close the link, open the official login route independently, and use OpenAI’s login troubleshooting guidance if the problem continues.

Use the same checks for any AI service: verify the actual hostname, compare it with the provider’s official web address from a source you trust, and navigate to sign-in independently. Don’t treat a search ad, link preview, brand name inside a URL, or polished page as proof of ownership. If you cannot confirm the destination, don’t enter credentials there.

What should I do if I entered my password on a fake ChatGPT site?
- Go to the genuine account independently. Use a bookmark or type a trusted official address rather than returning through the suspicious message.
- Change the exposed password. If you reused it on other sites, change it there too. Use unique passwords; a password manager can help create and store them.
- End existing sessions. Log out of active sessions from the genuine account’s security settings. Turning on MFA alone does not end sessions already open.
- Enable MFA and review account security. Check security history and sessions for activity you do not recognize, and contact OpenAI Support if you suspect compromise. OpenAI’s account-security guidance covers password, session, and security-history steps.
- Protect other affected accounts. If you also submitted a verification code or reused the password elsewhere, secure those accounts through their official sites as well.
Which sign-in protection should I use?
Multi-factor authentication (MFA) adds a second check beyond a password, but available methods vary by device, country, account tier, and setup. OpenAI lists authenticator apps, push notifications, text messages, and passkeys in its MFA guide. These methods are not equally resistant to phishing: a code entered into a fake page can be captured, so destination checking still matters.
OpenAI’s Advanced Account Security option requires passkeys or physical security keys and disables password login for eligible accounts enrolled in that option (OpenAI announcement). Check eligibility and the account’s current setup before relying on a particular method.
A physical key, such as the YubiKey bundle OpenAI names for eligible users, can strengthen sign-in protection. It is optional and is not a detector for fake websites: inspect the destination before entering any account information. Consider recovery as well—keep a secure backup method available so losing a device or key does not lock you out.
