Creating SMS OTP Based Login System

Hi All,

I am trying to build an SMS OTP based login system for my application.

From what I have read, I have two options, Firebase Auth and Auth0. Which one of the two is more suitable for Bubble? Are there any other better options?

Use-cases that I want to cover are these:

  • Users should be able to login via SMS OTP, or Email, or Google/FB

  • Need to handle scenarios of user first registering/signing-in with one method and then later on signing in with other method (merging two identities etc.)


Bumping it up to catch some wise folks’ eyes.

Any luck with it?

Nope. I had put it on hold too. Will restart the effort soon.

From my last time’s effort I realised that I can do it via Firebase, but was struggling with firebase integration.

More bumps!!! Hope someone enlightened sheds some light!

Hey all,

I’m not sure if there’s exactly one better than another because I haven’t implemented SMS OTP before; however, I’ve heard good things about Auth0 and am sure you can probably implement it with the API connector.
