Claude Account Login and Switching Guide: Email Verification, Logging Out and Back In, and Keeping Your Data Intact

To use Claude smoothly, the most hassle-free approach is to first sort out your login method and account switching. Below, I’ll explain the real steps clearly: how to log in with email verification, how to safely log out and switch accounts, and common pitfalls that make it seem like you’re “logged into a brand-new account” after signing in.

Which login methods does Claude support? Choose the right entry point first.

Claude’s common login entry is the official website’s sign-in page. It generally supports email verification-code login and third-party account login (such as Google). It’s recommended that you stick to one method long-term; switching devices later will be more stable.

If you log in with email today and switch to a third-party login tomorrow, even if the email looks the same, the system may recognize you as a different identity, causing your chat history in Claude not to appear. To avoid confusion, try to keep using the same Claude login method.

Logging into Claude with an email verification code: What to do if you don’t receive the email

After selecting “Log in with email,” enter your email address and request a verification code, then return to the page to complete verification to enter Claude. The code usually arrives within a few minutes; first check your spam folder and the Promotions/Subscriptions categories.

If you still don’t receive it, try again under a different network environment and make sure your email account hasn’t enabled overly strict blocking rules. If necessary, wait a moment and resend the code, avoiding frequent clicks that may trigger rate limits.

How to safely log out of Claude and switch accounts

To switch Claude accounts, the most reliable method is to log out within the page first, then log in again with another account. If the browser still automatically returns to the old account after you log out, it’s usually because cache or a third-party login has kept the session.

The fix is simple: open an incognito/private window to log into the new Claude account, or clear cookies related to the Claude site in your browser. This makes the account switch cleaner and reduces cases where you “jump back to the original account.”

Avoid losing conversations: Confirm these two things before switching accounts

Before you log out of Claude, first confirm that the current conversation has fully loaded successfully, to avoid display issues caused by network lag. If after switching you find that “the conversations are gone,” first check whether you changed the login method or logged into a different account.

If you use Claude on multiple devices at the same time, it’s recommended to use the same login method on each device and bookmark the Claude login page in your browser for direct access. That way, whether you’re switching computers or switching accounts, you’re less likely to mix things up.
