Method 3) SuperTokens SMS service
Using this method, SuperTokens will send SMSs to your users automatically. Use this method if:
- You are already using our managed service - this is the quickest way to setup SMS sending.
- You want to take advantage of some of the SMS sending optimisations we add over time:
- Reduce SMS cost by picking a local SMS service based on the destination country.
- Fight spam / misuse of SMS.
important
This is a paid service and we charge for every SMS based on the cost we incur. We give new users $10 worth of credits.
#
1) Get the SMS API key- Sign up on supertokens.com
- Create a new development env
- Scroll down and create a new production env (it takes a few minutes to create one)
- Once the production env is created, you can find your SMS API key under the setup section:
![](/img/passwordless/sms-api-key.png)
#
2) Set the SMS API key in the backend SDK config- NodeJS
- GoLang
- Python
- Other Frameworks
Important
For other backend frameworks, you can follow our guide on how to spin up a separate server configured with the SuperTokens backend SDK to authenticate requests and issue session tokens.
