Stuck at login or not receiving 2FA codes on Claude? Don't reset your password just yet. Here are the most common login error symptoms and step-by-step fixes to get you back in quickly—without submitting unnecessary account appeals.
Email Verification Code Not Received
Many users don't get the verification code within minutes during signup or after switching devices. First check your spam folder—Claude's verification emails are sometimes flagged as spam. If it's missing, request a resend but avoid clicking more than three times in a row, or you may trigger temporary risk control. Try switching to a different network (e.g., Wi-Fi vs. mobile data) as some carriers block overseas emails.
Two-Factor Authentication (TOTP/SMS) Fails
If the dynamic code always shows as invalid after enabling 2FA, first confirm your phone's time is synced with the network. Many authenticator apps rely on timestamps; a deviation of more than 30 seconds will cause verification failure. Manually calibrate the time in system settings, or re-scan the QR code with Google Authenticator to sync again. If the issue persists, use a backup recovery code to bypass 2FA, then revoke and re-bind the authenticator from your account settings.
Correct Password but Login Keeps Failing
If your password is correct but you keep getting an error, your account may be temporarily locked or the IP address flagged. Claude imposes short-term bans on IPs with repeated login failures. Wait 15 minutes and try logging in from a different network (e.g., your phone's hotspot). Also check if third-party proxies are enabled—some regional nodes are blocked by Claude's security policy. Disable all network tools and try again. If it still fails, check your registered email for any security notifications from Claude that may require device confirmation.
"Account Doesn't Exist" or "Please Sign Up" Message
Entering the correct email but seeing "account not found" likely means you used a different login method (Google account vs. email/password). Claude supports multiple identity sources—if you originally registered via Google and later try email login, it will show as missing. Use the "Forgot Password" option to retrieve account info, or select "Continue with Google" on the login page to verify ownership. If the account was indeed deleted, you'll need to register again.
Session Expired and Can't Auto-Recover
Claude sessions last a long time, but after prolonged inactivity or network changes, the web interface may get stuck on a "Reconnecting" screen. Instead of refreshing, clear your browser cache and cookies first, then revisit the Claude website and log in again. Some users report that incognito mode resolves the issue because it doesn't load old session data. If the problem persists, check whether your browser blocks third-party cookies—allow Cookie writes for the Claude domain.
