The official link
Use https://chatgpt.com/auth/login for ChatGPT sign in. If your browser redirects through an OpenAI authentication domain, check that the address belongs to OpenAI before entering your password.
Before you type a password
Look at the address bar, avoid sponsored lookalike pages, do not trust copied login links from unknown emails, and never reuse your OpenAI password on unrelated sites.
If login does not work
Try a private browser window, clear cookies for ChatGPT, disable extensions, check whether your VPN is interfering, or use the official mobile app. Do not create risky workarounds with shared accounts.
How to use this page
Use this page as a decision checkpoint. First verify whether you need the official ChatGPT website, then decide whether you need login help, safety checks, app guidance, alternatives, paid-plan advice, troubleshooting or privacy guidance.
What to verify on official pages
For accounts, pricing, limits, apps, policy, data controls and billing, always verify on official provider pages. Guides can explain the workflow, but the provider controls the final terms.
Common mistakes
Do not search for a login every time if you can bookmark the official URL. Do not assume that a tool with ChatGPT in the name is operated by OpenAI.
When alternatives make sense
Alternatives can help when ChatGPT is down, when you need citations, when you work in Google or Microsoft products, when you need a different writing style, or when you want to compare several models side by side.
A safer workflow
Keep sensitive data out of random tools, separate personal and work accounts, check company policy before uploading files, and verify important facts before publishing or sending any AI-assisted output.
