Login using phone number

User Service
1

Hello Backendless! Thanks for amazing service.

My team has built a service using Backendless but decided to switch from email login to passwordless login using phone number. We found that it’s not so easy to implement. There is an integration with Twilio, but it doesn’t suit or case for three reasons:

  1. There are separate methods for login and registration, but would like to use single passwordless login for new and old users.
    2.Twilio SMS cost is too big for our country.
  2. Our country is also in the list of countries which requires extra $250/mo fee for sms receiving.

Maybe there is another integration which better fits our case?

We’re also thinking of using our sms provider. We’ve setted backendless methods to communicate with it and it works good, but we can’t login the user on mobile side because there are no mobile SDK methods to login the user without email. We also were thinking of using codeless method for passwordless login and sending auth token to mobile side, but not sure if it is possible.

Is there a way to implement passwordless login with phone number using our 3rd party sms provider?

Thanks
Edward

Hello,

You can implement the login with phone number flow the same way we did with Twiliio. We didn’t use any special APIs for that. The integration with Twillio is done using all the same facilities of Backendless that are available to you as well.

I recommend you studying Login APIs, Cloud Code (event handlers) and you should be able to come up wiith a solution. Good luck.
