Problem
Store owners regularly run into problems with customers forgetting passwords and customers abandoning carts simply because the login process is too cumbersome and cumbersome and causing customers to reset passwords, frustration, and abandonment rates to jump.
Also, for admins, logins without authorisation from bots and attacks on the store for fraud impact the store's reputation and the trust of their customers. Not having a secure passwordless login experience creates friction for customers on the way to their accounts and for merchants that are simply trying to protect them.

Likewise, there is full customisation for the widget presentation and OTP templates, so merchants can maintain a strong brand identity while improving access control. Whether you are fighting against login fraud or are focused on improving user experience and satisfaction, this app offers a modern, fast, and simple login flow.
