There are two methods supported currently: Text Message and Authenticator App. We recommend using the Authentication App as it is more reliable than Text Message and it does not require data connectivity to function. Keep checking back though – we are definitely looking to have more options in the near future!
Here is a non-extensive list of authenticators that you can use:
- Google Authenticator
- Microsoft Authenticator
- Authy
- Duo Mobile
