Yes, this is a solution for gmail login challenges.

In the slack app you create a phone number, then you register that phone number with your google account. From now on any login challenge you receive on that phone number will be sent to slack.

If you have a team of multiple people, they would all be able too see and use that code if they triggered it.

This is much better than having to ask the person who's phone number is associated with the gmail account. As they may not answer in time.
