Since Edge doesn’t allow disabling certificate validation through flags/switches when launched normally, here is an easier way to run it in insecure mode ignoring certificate errors:
- Create a shortcut for Microsoft Edge on your desktop
- Right click the Microsoft Edge shortcut > Properties
- In the Target field, add
--ignore-certificate-errors
to the end after a space. - For example:
"C:\Program Files (x86)\Microsoft\Edge\Application\msedge.exe" --ignore-certificate-errors
- Click Apply then OK.
Now when you launch Edge from this shortcut, it should start ignoring any SSL certificate errors for all sites and allow access to them without any warnings.
Good Luck
