firebase::auth::PhoneAuthOptions

Sets the PhoneAuthProvider::ForceResendingToken to force another verification SMS to be sent before the auto-retrieval timeout.

If nullptr, assume this is a new phone number to verify. If not-NULL, bypass the verification session deduping and force resending a new SMS. This token is received in PhoneAuthProvider::Listener::OnCodeSent. This should only be used when the user presses a Resend SMS button.

The phone number for sign-in, sign-up, or second factor enrollment.

The maximum amount of time you’re willing to wait for SMS auto-retrieval to be completed by the SDK.

This value is supported on Android devices only.

The minimum timeout is 30 seconds, and the maximum timeout is 2 minutes. If you specified a positive value less than 30 seconds, the SDK will default to 30 seconds. Specifying a timeout that is greater than 120 seconds will result in an IllegalArgumentException being thrown.

Use 0 to disable SMS-auto-retrieval. This will also cause PhoneAuthProvider::Listener::OnCodeAutoRetrievalTimeOut to be called immediately.

Sets the context to which the callbacks are scoped, and with which app verification will be completed.

On Android, the context should be a jobject referencing an Android Activity. On Apple platforms, this should be a pointer to UIView. For any other platforms, the context is ignored.

If ui_parent isn’t defined (ie: nullptr or nil) then the FirebaseApp’s default Activity or UIView will be used.
