This is the best app for OTP login. Working with Extendons we were able to develop an unusual workflow that was required for our website. The team at Extendons was quick to respond and implement our unique requirements. Great team to work with would recommend them to anyone looking for an OTP app.
We are using this app from couple of months, working smoothly and there was one issue recently, the support team was very quick and resolved it on priority. Happy with Service
Super helpful! Whenever I ask for customizations or anything related to configuration, their responses are incredibly clear and very fast. Setting up the mobile OTP login page took only about two days thanks to their support. Highly recommend!
It has some very useful features like the instant pop-up on pressing 'buy it now', and the app has customization of what you want to communicate at every state of the logging in process. It pretty much solves all our problems as we were struggling with other apps earlier. Their support has also been very prompt in resolving few issues we had.
We've been using Extendons on our site, and it's been a great addition. The plugin adds an extra layer of security with OTP verification, which has worked well for us by reducing the risk of spam accounts and improving user trust. When we needed some customization, the support team was responsive and helpful in making the necessary adjustments. Overall, it's a reliable tool that meets our needs, with good support for customizations.
We have been using this app for OTP login for a couple of years now. This app has worked very well for us. Recently, we faced some issues with Google firebase, and their team replied to the queries on WhatsApp, and provided solutions almost immediately. Extremely impressed. Best of luck.
Awais has been very helpful in immediately responding and giving solutions! We have searched for 20+ apps but all were complicated! This app is simple and does the work so thank you for that! OTP verification pre-checkout is possible with this app and we are super happy.
Extendons team is really swift in taking care of the requirement. I needed email OTP verification during sign up and they have helped me implementing it very smartly. Their customer support is really good.
