Claude User Guide: Full Process for Account Registration, Email Linking, and Security Verification

This tutorial only covers the basics of getting started with Claude: how to register, complete email verification, manage logged-in devices, and what to do if you don’t receive the verification email. Follow the steps, and you’ll be able to log in to Claude reliably and switch between your commonly used devices.

1. Register a Claude account on the web

Open the official Claude site (claude.ai). Click Log in/Sign up, then choose email registration or sign in with a third-party account. If you register with email, it’s recommended to use an email address you use regularly—future verification and account recovery will be much easier.

After entering your email and password and submitting, Claude will guide you through the remaining verification steps. If the page indicates additional verification is required (such as a code or extra checks), follow the prompts. Avoid refreshing repeatedly to prevent triggering risk controls.

2. Complete Claude email verification and “link” your account

After registering, check your inbox for the verification email and open the verification link to confirm. This step effectively links your Claude account to your email address. Once verification is complete, return to the Claude page and refresh once—usually you’ll be taken directly into the chat interface.

If you’re using a work or school email, it’s recommended to also check folders like Spam/Junk, Quarantine, or Security Review. Some inboxes may delay delivery; waiting 1–3 minutes before trying again is often more reliable.

3. Using Claude across multiple devices and switching accounts

When logging in on different devices, using the same browser account system will let you continue using the same Claude account seamlessly. If you need to switch accounts, log out in the Claude interface first, then log back in with a different email/method to avoid overwriting and causing conversation confusion.

If you often use Claude on public computers, it’s recommended to log in using an incognito/private window. When finished, log out immediately and close the window to reduce the risk of automatic sign-in caused by leftover local cache.

4. Common issues: Not receiving emails and troubleshooting login problems

If you don’t receive the verification email, first confirm the email address was entered correctly, then check Spam/Junk and categories like Promotions/Subscriptions. If it’s still not there, return to the Claude page and resend the verification email. Some email services block verification emails containing links; registering with a different email address usually resolves it quickly.

If Claude keeps redirecting during login or the page is blank, first clear your browser cache and cookies, or try a different browser/network environment. If you see prompts that the account is restricted or cannot be verified, follow the on-page instructions to submit an appeal/contact support, and avoid repeated login attempts in a short period to prevent stricter restrictions from being triggered.
