What is auth.openai.com?
ChatGPT login can redirect through official OpenAI authentication domains. The important part is knowing which domains are legitimate before typing a password.
This page never collects passwords. Use it as a checklist, then sign in only on official domains.
Intent
What this page solves.
User sees auth.openai.com and wonders if it is safe.
Check exact spelling
Phishing sites use extra words, hyphens, misspellings, or strange endings. Do not trust a page because it merely contains “openai” somewhere.
Use password manager clues
A password manager usually offers saved credentials only on the real domain. If it does not, stop and inspect the URL.
Return through chatgpt.com
If in doubt, close the tab and type chatgpt.com manually instead of following search ads or random links.
