Phone Auth with MessageBird
- A MessageBird account (sign up here)
- A Supabase project (create one here)
- A mobile phone capable of receiving SMS
Set up MessageBird as your SMS provider
Start by logging into your MessageBird account and verify the mobile number you'll be using to test with here. This is the number that will be receiving the SMS OTPs.
Navigate to the dashboard settings to set the default originator. The messagebird originator is the name or number from which the message is sent. For more information, you can refer to the messagebird article on choosing an originator here
You will need the following values to get started:
- Live API Key / Test API Key
- MessageBird originator
Now go to the Auth > Providers page in the Supabase dashboard and select "Phone" from the Auth Providers list.
You should see an option to enable the Phone provider.
Toggle it on, and copy the 2 values over from the Messagebird dashboard. Click save.
If you use the Test API Key, the OTP will not be delivered to the mobile number specified but messagebird will log the response in the dashboard. If the Live API Key is used instead, the OTP will be delivered and there will be a deduction in your free credits.
Plugin MessageBird credentials
Now the backend should be setup, we can proceed to add our client-side code!
SMS custom template
The SMS message sent to a phone containing an OTP code can be customized. This is useful if you need to mention a brand name or display a website address.
Go to Auth > Templates page in the Supabase dashboard.
Use the variable
.Code in the template to display the code.
