In my small town there is a competing company that sells the same items that our store does but they charge less than we do so they are stealing our clients. We want to know if there is a way to block an access to logging in at certain location? We are not afraid to lose clients by blocking the access because in this area only those sellers live. Clients 100% come from different cities.
We don't detect on login specifically, but my app Blockade allows you to block by country, IP address & VPN usage.
It's free up to 3 countries, than $5 per month for unlimited countries, IP addresses & VPN detection.
