We were worried about bot accounts and fake registrations inflating our customer list. The browser and bot detection feature in OTP+ caught a surprising number of suspicious sign-ups in the first week. The detailed logs make it easy to review and act on.

OTP+ replaced a clunky third-party login solution we had cobbled together. The difference in how polished the login experience feels now is night and day. Customers compliment the checkout flow regularly now, which is something I never expected to hear about a login screen.

All I can say for now is that this was the easiest install ever! It’s so simple to navigate—clean, straightforward, and nicely designed. I just wish I could preview what it looks like right after installation to see exactly what my customers will experience. I'll be back in the next week or two for a full update.
