When you sign up for a Sinch Account on the Sinch Build Dashboard you need to provide a phone number as part of the sign-up process. Sinch will verify this phone number and once it has been successfully verified, your phone number will be used for:
- Two Factor Authentication (2FA Security)
- For sending test messages.
If you want to change your number, it depends on your use case:
- To change the number you are using for 2FA (for example, if you get a new phone number or have lost your phone) – follow the process outlined in the article: How do I configure 2FA in the Sinch Build Dashboard?
Note: You cannot directly change your phone number associated with 2FA. The only way to do this is to deactivate 2FA and then to reactivate it using a new number. Follow the steps in the linked article above.
- For testing and sending messages during trial periods you can have multiple numbers – the first of which will be the number that you provided as part of the sign-up process. To change this number, follow the instructions in the link provided above above.
To add a new number for testing follow the steps in article: How can I add a verified number to my account?
