We’ve had a great experience using Lucent OTP Login & Notify. The app works well and has been reliable for what we need. Their team has also been very helpful anytime we’ve needed customizations or had questions. They’ve been responsive, easy to work with, and willing to help us get things set up the way we needed. Overall, it’s a great app with great support, and we really haven’t had any issues. Highly recommend.

We received excellent and dedicated support from Varun and the Lucent team. They were highly responsive in implementing our customisation requirements and provided valuable guidance on the integration of our preferred SMS OTP provider promptly. The team assisted us to configure the register/login modals and profile/account pages to align precisely with our desired UI/UX. Overall, we are very satisfied with the quality of support delivered. Much appreciated.

I had a great experience working with the Lucent OTP application. The platform is efficient, reliable, and integrates seamlessly, making the overall authentication process smooth and user-friendly. A special mention goes to Mr. Varun, who has been extremely supportive throughout the entire integration process. He assisted me in every way possible, ensuring that all challenges were addressed promptly and effectively. His responsiveness, technical expertise, and willingness to go the extra mile made the implementation truly hassle-free. Thanks to his continuous support, we were able to complete the integration smoothly without any major issues. Overall, I highly recommend the Lucent OTP solution for anyone looking for a dependable OTP system backed by excellent support.

Great app for adding SMS and WhatsApp OTP based logon to the store. Works exactly as desired. Loved the flexibility they provide. Was able to configure my own sender id. Was also able to create a login popup. Support is mostly over emails and so takes a few hours to respond but they do respond and resolve issues, if any.

We've been using Lucent for a week now, and it's been a great experience so far. The installation process was quick and seamless—special thanks to Varun from the team, who was extremely helpful and prompt in following up and getting everything set up efficiently. It hardly took any time to get started. The pricing is also very reasonable, especially for small businesses like mine. If you're looking for a reliable OTP login solution, I recommend exploring Lucent. Thanks!

It was an awesome using this app increased our website value using mobile number log in to the customer account. The main thing is extreme support and also instant support for whatever is my changes they will be done as per my requirement. Overall i recommend this app for shopify users.

We had a good experience working with them. We were facing an issue from 2 months and Mr. varun from the team helped us really well to get rid of it. The app is very useful for us to maintain the user login on our shop. Highly recommended.

This app has been super helpful to get our OTP login customized as per our requirements.. we had to go through setup of Airtel DLT and the team guided us how to do this as well. Thanks!
