This tutorial only covers basic Claude account operations: how to register, how to log in on different devices, and how to safely switch accounts and log out. The process isn’t complicated, but many people get stuck on verification, browser cache, or using multiple accounts together. Follow the steps below and you should be able to start using Claude smoothly.
1. Claude Registration and First Login: From Entry Point to Verification
Open the Claude official website (claude.ai). After clicking Log in/Sign up, follow the on-page prompts to choose email registration or log in with a third-party account. When using email, Claude usually requires you to complete email verification, and the message may be in “Spam/Promotions.” After verification is complete, return to the page and refresh once—Claude will automatically enter the chat interface.
After entering Claude for the first time, it’s recommended that you immediately check whether the profile entry correctly shows your nickname/avatar. This confirms you’re logged into the intended account. If you’re using Claude on a company or public network, try not to select options like “Stay signed in.”
2. Managing Login Methods: Avoid the Misunderstanding That “Changing Email Means Changing Accounts”
Many people think that changing the email lets them “merge accounts,” but Claude’s login identity is usually bound to the login method you originally chose (e.g., a specific email login or a specific third-party account). If you want to change your login method, the most reliable approach is: first confirm whether there are important chat records or projects in the old account, then decide whether to create a new account and migrate.
If you often use Claude for work, it’s recommended to stick to one login method and keep a consistent account setup within the same browser (e.g., using only one browser profile). This reduces situations where “you’re clearly logged in but find that your content is gone.”
