As a security feature, Modern Retail locks users out of the Admin Panel after several failed login attempts. In this article, we'll talk a little bit more about how this works, why we do it, and how users can get un-locked.
Users are automatically unlocked 5 minutes after their final failed login attempt. This prevents brute force attacks (trying every conceivable password possibility) while preventing any inconvenience for users.
If you have any additional questions, please feel free to contact us with a support request from the Admin Panel.
