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.

STOP using or installing. If you use this application, be prepared that your credentials from Firebase and MSG91 will be visible to the whole world. And anyone can use your authorization data and reset your balance. Our security department did it in two minutes: - to find out that 162 stores were connected through them. - 66 of them have Firebase credentials and some of them have msg91. Contact Shopify for more details.

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.
