Before trying either route, identify the exact email attached to the account containing your conversations. Being able to open a new chat under a different address would not recover that work.
Match the login to the account you already use
If Claude is still open on your phone, check the account address there. An address used for a purchase, a browser profile or a forwarded email may not be the Claude sign-in address.
Suppose a fictional user requests login on a laptop but reads mail on a phone. They click the message on the phone, see a code, then keep waiting for the laptop to sign in automatically. The missing step is entering that code on the laptop where they started the request.
Complete the email route on the original device
Enter the account email, choose Continue with email, and locate the message titled Secure link to log in to Claude.ai. Opening it on the requesting device signs you in there. Opening it on another device produces a verification code to enter on the original one. Same-device and cross-device behavior
For the laptop-and-phone example:
- Start the login request on the laptop.
- Open the received login message on the phone.
- Follow the link and read the verification code it provides.
- Enter that code into the waiting login flow on the laptop.
- Check that the laptop opens the expected account and conversation.
Keep the code within that login flow. A person claiming to provide support does not need you to paste it into a chat or email.
Diagnose a missing email before requesting more
Look in spam, junk and your organization's mail quarantine. Anthropic identifies @mail.anthropic.com as the sender domain to check and allow in mail settings. Managed business, government or education mail may require an IT administrator's help. Email delivery troubleshooting
Keep the observations separate:
| Observation | Next check |
|---|---|
| No login message arrives | Exact account email, spam and quarantine |
| A message arrives but the laptop stays signed out | Whether the link was opened on another device and supplied a code |
| Login succeeds but familiar chats are missing | Account address and selected personal or organization account |
| A link or code returns an error | Exact error and Claude's service status before further retries |
Repeatedly requesting messages without checking the address or quarantine does not identify which step failed. Wait a few minutes before another attempt, following Anthropic's guidance.
Check an Apple relay address if you used Hide My Email
If the account was created with Apple's Hide My Email, use its @privaterelay.appleid.com address with Continue with email. The secure link goes to your Apple ID email. In Claude for iOS, the account address is visible in Settings after selecting your initials. Apple relay login
Do not replace the relay address with a different personal address and assume it identifies the same account. If the real problem is an address you can no longer access, Claude's email-change guide explains the current limitation and support route.
After signing in, open one recognizable conversation and read its contents. That confirms you recovered the work you needed, rather than merely reaching a working login screen.
