ChatGPT Tutorial: How to Sign Up and Manage Multiple Accounts (Step-by-Step Guide)

ChatGPT is one of the most popular AI conversation tools today, but many beginners get stuck during registration or when switching between accounts. This tutorial walks you through the entire process—from sign-up to managing multiple accounts—with no programming experience required. Just follow the steps and you'll be up and running.

Email Registration & Identity Verification

Start by opening the official ChatGPT website and clicking the "Sign Up" button. We recommend using a Gmail or Outlook email address—domestic QQ mail sometimes fails to receive verification emails. After entering your email, the system will send a verification link. Click it to proceed. You'll then need to set a strong password that includes uppercase and lowercase letters and numbers, with a minimum length of 8 characters.

Once your email is verified, you'll be asked to bind a phone number. ChatGPT restricts phone numbers by region—numbers from mainland China, Iran, Russia, and a few other countries are currently not supported. You can use a virtual SMS reception service (e.g., sms-activate.org) to purchase a temporary number from a supported country, which usually costs around 1–3 CNY. Make sure to select "OpenAI" as the service provider. After completing SMS verification, you'll be taken to the ChatGPT main interface.

Logging In & Switching Accounts Across Devices

To log in, simply enter your email and password on the website, or use the Google/Microsoft account quick-login option. If you need to use ChatGPT on both your computer and phone, just log in with the same account on different devices—your chat history will sync automatically.

To switch accounts, you'll first need to log out: click your profile picture in the bottom-left corner and select "Log out." Then enter the email and password for your other account. We recommend using Chrome's multi-user profile feature—assign one ChatGPT account to each profile so you can switch instantly without re-entering credentials.

Common Issues & Important Notes

If you see the message "OpenAI's services are not available in your country" during registration, it means your IP address is blocked. Switch your VPN to a supported region (e.g., the United States, Japan, or Singapore), and make sure the IP is stable—avoid frequent switching. Also, keep in mind that one phone number can only be bound to a single ChatGPT account; attempting to bind it a second time will result in an error.

If you forget your password, click "Forgot password" on the login page, enter your registered email, and the system will send a reset link. If you don't receive the email, check your spam folder or try a different email address. Keep your browser up to date to avoid compatibility issues that may cause page lag.
