Google: "Allow less secure apps: OFF" required for Zoho Access

Google: "Allow less secure apps: OFF" required for Zoho Access

Today I change my Google setting to "Allow less secure apps: ON"  Suddenly the warning messages came in because Google considers Zoho mail less secure.  I was no longer able to access GMAIL via Zoho.  Is there a way I can keep "Allow less secure apps: ON" and still use Zoho mail to manage my GMAIL account?
