My only problem dropping a smartphone has been there is no alternative for authenticators. I have a few authenticators including:

Google authenticator, Okta Verify, Battle.net authenticator, ESET Secure Authentication and SecureAuth.

While I might be able to find an alternative for the Google authenticator on a dumb phone, I feel it's unlikely for the others.

Hi, author here. This is a good point. I also have an authenticator that I was not able to replace. However, I need it very infrequently (a few times a year) and never in a time-sensitive manner. So I can just afford to turn on my smartphone for a couple minutes whenever I need the authenticator, and then turn it back off.
