Called once auto_verify_time_out_ms has passed. If using auto SMS retrieval, you can choose to block the UI (do not allow manual input of the verification code) until timeout is hit.
SMS message with verification code sent to phone number.
Called immediately after Auth server sends a verification SMS. Once receiving this, you can allow users to manually input the verification code (even if you're also performing auto-verification). For user manual input case, get the SMS verification code from the user and then call GetCredential with the user's code.
Details
Parameters
verification_id
Pass to GetCredential along with the user-input verification code to complete the phone number verification flow.
force_resending_token
If the user requests that another SMS message be sent, use this when you recall VerifyPhoneNumber.
