We have used this app for our digitally launched products, and it is fantastic. It provides a variety of different options to help us protect our resources. It is user friendly, and we have received excellent customer service. I would highly recommend this app. I know you will find the features applicable to your needs. Don't think twice. Get this app!

Works well with lots of options for different scenarios. Can be complex to set up but if you have a question, a real person will respond to you very quickly with good advice. It's expensive considering that basic locking features should come with every Shopify plan, in my opinion. The search tool to start a new lock can be very slow, to the point where it freezes completely. Apparently this is a problem on Shopify's end, but I wish that there was a way to filter before beginning a search; such as, search only products (or collections) for the term ___. I also wish you could lock tags. All that said, we've been using the app for over a year now with no problems.

I use this app to send password protected links to customers so they can order custom items or products that we don't want anyone browsing the website to see. It's simple, intuitive and it works smoothly and accurately, with fast customer service.
The only thing that would be a nice extra feature would be the ability to search for locks that have been created rather than having to scroll through alphabetically to find the one you want.
