How to Change Claude Login Email Address

Unlike many web platforms, Anthropic’s Claude interface does not currently offer a self-service "Change Email" button in your account settings. Because Claude uses third-party identity providers (like Google Sign-In) and passwordless magic links to secure your account, login credentials are tied directly to the unique identifier of the email you registered with.

If you have changed jobs, lost access to your primary inbox, or simply want to clean up your login details, you must use a specific workaround to transition your subscription, save your data, and register a new email.

Here is a complete, step-by-step guide to updating your Claude login email without losing your subscription or getting your phone number locked out.

Why You Cannot Directly Change Your Claude Email

Claude’s authentication system relies on Auth0 and strict identity verification protocols. Your account history, billing profile, and API usage (if applicable) are permanently mapped to your original signup email.

Because of these security protocols, modifying your login email requires creating a new account. However, you cannot simply sign up again with your current phone number, as Anthropic limits one active account per phone number to prevent spam. You must follow the steps below in the exact order listed to avoid account locks.

Step 1: Cancel Your Existing Claude Pro Subscription

If you have a paid Claude Pro subscription on your old email, you must stop future payments on that account before setting up your new one. Subscriptions cannot be directly transferred from one email to another.

1. Sign in to Claude using your old email address.
2. Click on your profile initials in the bottom-left corner of the dashboard.
3. Select Settings from the popup menu, then navigate to the Billing tab.
4. Click Manage Subscription to open the Stripe billing portal.
5. Click Cancel Plan and confirm the cancellation.

*Note: Your Claude Pro features will remain active until the end of your current billing cycle. To avoid double-billing, wait until the day before your cycle ends to complete the next steps.*

Step 2: Export Your Chat History (Optional)

Anthropic does not support direct chat migrations between accounts. If you have critical data in your current conversations, you must manually export it.

1. Open the chats containing information you need to keep.
2. Copy and paste the text into an external document editor (such as Google Docs, Notion, or a local markdown file).
3. If you use the Claude API, ensure you copy any custom system prompts or API keys, as these will not transfer.

Step 3: Delete Your Old Claude Account

To register your new account, you must free up your mobile phone number. If you attempt to register a new account using the same phone number while the old account is active, you will trigger an error or face a suspension.

1. In your old Claude account, click your profile icon and go to Settings.
2. Navigate to the Account tab.
3. Scroll down to the bottom of the menu and click Delete Account.
4. Type the confirmation phrase exactly as requested (usually your email address or "DELETE").
5. Click Delete Account to permanently purge the profile.

*Warning: This action is immediate and irreversible. All chats, settings, and subscription history associated with this email will be permanently destroyed.*

Step 4: Create a New Account with Your Updated Email

Once the old account is deleted, your phone number is instantly released and can be used to verify your new email.

1. Navigate to the Claude signup page (claude.ai/login).
2. Enter your new email address or select "Continue with Google" using your new Google account.
3. Open your new inbox, locate the login link sent by Anthropic, and click it to verify your email.
4. When prompted for phone verification, enter your mobile phone number.
5. Input the SMS verification code sent to your phone to complete registration.
6. Go to Settings > Billing to re-subscribe to Claude Pro if desired.

When to Escalate

You should contact Anthropic customer support in the following scenarios: * You no longer have access to your old email address and cannot log in to cancel your paid Claude Pro subscription. * Your phone number is flagged as "already in use" even after you deleted your old account. * You require corporate SSO or bulk team email changes under an active Claude Team plan.
