Claude Account Registration & Email Verification Code Login Guide: Create, Log Out, and Switch Accounts

This tutorial only covers the registration and login process on Claude’s web version, and clearly explains “how to switch accounts” and “how to avoid repeated verification” in one go. Follow the steps and you can usually create a Claude account and use it steadily within a few minutes.

Before entering the Claude sign-up page, prepare two things

Open your browser and visit Claude’s official site (usually claude.ai). Confirm the domain in the address bar is correct before continuing. Prepare an email address that can receive messages normally, and make sure verification-code emails won’t be automatically sorted into “Spam/Promotions”.

If you often use multiple Claude accounts on the same computer, it’s recommended to separate logins in advance using “browser profiles/separate users”. This keeps Claude’s cookies and sessions from mixing, making account switching much easier later.

Claude registration and login: the correct way to use email verification codes

A common method for Claude is “enter email → receive a one-time verification code → return to the page to complete login”. The code is usually time-limited, so it’s best to paste it immediately after receiving it to avoid it expiring due to switching back and forth between apps.

If Claude says the verification code is invalid, first check whether you entered a code from an older email, then click resend once. If it still doesn’t work, refresh the page and go through the login process again—don’t keep submitting repeatedly on the same page.

How to log out and switch Claude accounts (without mixing them up)

In the top-right of the Claude page, go to Settings or the account menu, find “Log out/退出登录”, then log in with another email—this is the most reliable way to switch accounts. If the page still shows the old account after logging out, it’s usually because the cache hasn’t updated; refresh once or reopen the tab.

An even more hassle-free approach is to use different browser profiles for different Claude accounts, or use an incognito window for temporary logins. This way, you can use Claude account A in your main window while using Claude account B in another profile, without affecting each other.

Not receiving the verification code & page issues: troubleshoot by priority

If you’re not receiving the verification code from Claude, first check the spam folder and “Promotions/Subscriptions” categories, then whitelist the sender and resend. Corporate email systems sometimes block external verification emails; switching to a commonly used personal email often resolves it faster.

If the Claude page loads blank or buttons don’t respond, first disable script-related extensions or ad blockers, then clear the site’s cookies and log in again. If the page says the service is unavailable, it’s usually related to the region of the account or the service availability scope; refer to Claude’s official availability information and support channels for the most accurate guidance.
