Hi @VirginiaVet.

Your screenshot helps me understand your situation to enable Gmail enhanced security. I can assist change your default browser to what Gmail security is supported.

In your case, you'll have to change the default browser since the browser the system is using isn't compatible with enabling Gmail enhanced security. QuickBooks Desktop runs Internet Explorer browser services to view websites. To change this, we'll have to copy the Google Chrome shortcut found on your computer desktop and paste this into your App Data Windows Accessories.

Here's how:

1. Press the button Windows + R.
2. Type %AppData% and then press Enter.
   
   
    
3. Select the View tab and then check the Hidden Items option.
   
   
    
4. Then follow this step-by-step Microsoft>Windows>Start Menu>Programs>Windows Accessories.
5. From your desktop, copy (Ctrl+C) the Google Chrome shortcut.
6. Then paste (Ctrl+V) it into the Windows Accessories folder.
7. Once done, Right-click Internet Explorer and then select Rename.
   
   
    
8. Type Internet Explorer_OLD and then hit Enter.
   
   

Once done, try to close QuickBooks Desktop and rerun the application. Then go back to set up the Gmail enhanced security.

1. Go to the Edit menu and then select Preferences.
2. Choose Send Forms and then tick the Web Mail option.
3. Select Add.
4. Enter your Gmail email ID and then check the Use enhanced security box.
5. Click OK and then Continue.
   
   
    
6. Enter your credentials to enable enhanced security.
