WhatsApp Login Not Working? Try these tips

If you’re stuck trying to log into WhatsApp Web or Desktop, here are a few simple fixes that usually do the trick:

1. Check your internet connection
Sounds obvious, but it’s a common culprit. Make sure your phone has an active internet connection — even if you're logging in from your computer.

2.  Clear your browser cookies
Sometimes old cookies or cache can mess things up. Just head to your browser settings and clear cookies for web.whatsapp.com.

3. Update WhatsApp to the latest version
If you’re using an outdated version, certain login features like phone number login might not work. Fix this by updating your WhatsApp application.

4. Re-link your devices
On your phone, go to Settings > Linked Devices, tap the device you’re having issues with, and hit Log out. Then scan the QR code again to re-link.

5. Using VPN or firewall?
Disable it! Some VPNs or corporate firewalls block WhatsApp Web connections.

If none of these work, give it a few minutes and try again — WhatsApp services sometimes face short-lived downtimes.
