Claude AI can't log in – How to Fix
Try incognito mode, clear cookies for the service, disable extensions, and retry. If you use Google/Apple login, re-authorize the provider and check for outages.
Step-by-Step Fix
1. Try Incognito / Private Mode
- Open an incognito/private window
- Sign in again
2. Clear Cookies and Site Data
- Clear cookies/site data for the service
- Restart your browser
3. Disable Browser Extensions
Disable temporarily:
- ad blockers
- privacy/anti-tracking extensions
- script blockers
4. Switch Browser or Network
- Try another browser (Chrome/Safari/Edge)
- Try mobile hotspot to rule out network filtering
5. Re-authorize Google/Apple Login (If Used)
- Log out
- Start the login flow again
- Complete the OAuth prompt fully
6. Check for Outages
If there’s an outage, wait a few minutes and retry.
Common Mistakes to Avoid
- Troubleshooting the wrong account or workspace.
- Retrying without checking whether there is an active outage or plan restriction.
- Clearing local state only after multiple failed attempts instead of testing in a clean browser first.
What to Gather Before Contacting Support
- Capture the exact error message and the time it happened.
- Record whether the issue happens on another browser, device, or network.
- Note which account, workspace, or subscription plan is affected.
