Is it a good idea to backup your Authenticator app like Microsoft Authenticator? Or is it a security concern?

Context: I need to switch phones and I would like to avoid manually switching my 2FA to the other phone.

(I’m not looking for advise on the best 2FA physical token or app, I’m only looking for advise on if backing up for subsequently restoring the Authenticator app has any security concerns while switching phones)

Thank you.
