Hey! Definitely neat, and the idea that it gives you the convenience of OAuth without having to rely on a big provider like Facebook, Google, or Twitter is definitely a plus. Also interesting is it'll give me more trust in the product once you guys launch your paid version. (You know the old adage: "If someone's not paying for the product, then they are the product.") Are you folks planning on launching a bug bounty program? Since security is integral to a service like this, testing it for vulnerabilities will also be integral. Looking forward to where this goes!
will definitely be launching a bug bounty program, stay tuned. The paid product is about making it even easier again to login. Business/website will pay per user per month for that product, marginal cost.
but we will still keep the current product free as a feeder for the next!
Try out logging in with the Fast Button, it's like magic: Login first at Then try our one click login one any of Fast powered site, such as Got your own website? Put the Fast button on your site in 2 lines of code, and make it easy to login! -
Hey , first of all congratulations for the successful launch. While testing, I encountered this error
thanks, yes it seems the Shopify connector is returning errors. I have reported it thank you! Fast service itself is still running perfectly. Thanks!

Anything to remove steps for a new client is a step in the right direction.

Pros:

It’s so easy to install and allows our customers to log in and out seamlessly. Such a great UX.

Cons:

have not seen anything like it that works so smooth.

Easy login is always an issue, this is a great product. Failed logins are costing businesses alot more than they realize, great work!
Thanks Ben, the button would look great on IncoDocs! ;)
Its awesome work I had seen ever
Thanks, means a lot.
way better than typing name and personal info, skipping straight to the email confirmation!
100% - easy & secure!
This will really change everything about how we login to sites. It’s a no-brainer and can see this being widely adopted at a rapid rate.
Thanks Ryan, means a lot!
Looking great, I can't wait to see this out in the world with more and more platforms. Gotta think this is awesome for D2C brands too.
Absolutely, for eCommerce = gain sales and reduces cart abandonment, for SAAS increase retention and LTV!
Hey does it work with Firebase auth?
No native integration as yet, but our open API means you can integrate easily. Watch this space.
I have been waiting for something like this. How can it prevent users thinking the site is weakly secured? - Maybe the button needs strengthening up.
button is absolutely key to messaging, but we also leverage the trust of the host site. Bigger the network of installed sites, the bigger the inferred trust for the user.
