When using those apps, there are mandatory steps to do: backup 2FA codes (to recover later if your phones / devices broken and can not be prepaired), and test the validity of those backup codes (make sure that you make good backups and they can be used to recover).
Some screen shot the 2FA backup QR codes including the backup words and characters, some also store the back up on their phones notes, this is a poor and a non recommended way to back up 2FA codes, instead, you should do the paper printing, laminate it and put it in a place safe from damage and intruders(hackers)
We need to also be careful of hackers. Any device our wallets or our 2FA apps are installed, we need to make it safe from malware, trojan horse is able to reveal the 2FA code, also are some malware like rootkit that can reveal detail informations stored on your device, in this way, it can steal the 2 FA screen shot back up.
Make sure you decide is free from malware also, and do a paper printed 2 FA backup.
