Thank you so much to the OTP Login with Phone team. I contacted this wonderful team over two months ago, but due to some updates, I couldn't complete the integration of this fantastic application. When I contacted them again, I received the same friendly and helpful cooperation. Thank you!

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.

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.

I don't think they are capable of fixing the issues. I have recorded my screen and sent it to them and they have sent me an email telling me that issues were fixed on mac devices.. That wasn't even the issue. For the last few days, I have gained too much stress from them.

Good attempt but huge practical gap - App does not work for any customers who have previously purchased products from your store without registering/logging in using the app

— TRAPO® Car Mat Malaysia
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,...
