If you’re using an iPhone and you’re seeing this message popup:

Is this a problem for you?
Not a problem
If this is the first Authenticator account you’re setting up on your iPhone, there are no settings already backed up so nothing is changing for you.
You can safely choose Continue and continue with the steps on the previous page.
Maybe
If you already have a personal account setup in the authenticator app, the Authenticator app will not no longer back up your settings to the iCloud.
What settings? The authenticator app has a feature that allows you to save the Authenticator info (Passwords, account info) to the iCloud so when you get a new phone, and you transfer the Authenticator app (and all its configuration) from the old phone to new phone, making it makes for a seamless transition to your new phone. However this backup ONLY works for "personal" Authenticator accounts, not the "Work or School" account like our RRU account.

When the time comes and you get a new phone, when you install the Authenticator app you will need to install all your accounts (personal and RRU) again. Any password info will have to be re-imported.
It is STRONGLY recommended that you do not wipe your old phone before you re-add the accounts because, guess what? It will ask you to authenticate your account on your old phone, before your can add an account to the new phone.
