If you're new to Claude, the registration process, account linking, and switching between devices can feel confusing. This article breaks everything down into clear, straightforward steps—helping you go from zero to using Claude smoothly so you can start leveraging this powerful AI assistant right away.
How to Register a Claude Account: Email and Google Account Options
Go to the Claude website (claude.ai) and click "Sign Up" to access the registration page. Currently, there are two main ways to create an account: sign in with your Google account in one click, or enter your email address and set a password to complete the registration. If you choose email registration, it's recommended to use an international email service like Gmail or Outlook, as some domestic email providers may not receive the verification email. After submitting, the system will send a confirmation link to your email—click it to verify and activate your account.
Phone Number Verification: A Key Step for Security
Once registered, Claude usually requires you to link a phone number for security verification. Note: Claude currently does not support mainland China phone numbers. It's recommended to use a virtual number from regions like the US, UK, or Canada (e.g., Google Voice, TextNow). In the settings page, find the "Phone Number" option, enter your number, wait for the SMS verification code, and enter it to complete the binding. After linking your phone, you can also enable two-factor authentication (2FA) for extra account protection.
Switching Accounts & Multi-Device Sync: Manage Multiple Claude Identities Easily
If you have multiple Claude accounts (e.g., one for work and one for personal use), switching between them is simple. On the web version, click your avatar at the bottom left, select "Log Out" to exit the current account, then log in with another account. The mobile app supports the same process, and chat histories won't interfere with each other. Note that Claude currently doesn't have a built-in "quick account switch" feature, but you can achieve seamless switching by using your browser's multi-user profiles or different browser login states. Before switching, it's a good idea to confirm that important conversations from your current account are saved to avoid losing them.
