All people should somehow learn about wallets and what kind of wallet to use, only wallets where you can back up private keys or passphrase are good because only then you own the crypto and can always be recovered with private keys.
Indeed, this is the most important step in securing your wallet from loss or anything, but most importantly, don't easily trust anyone and any site because the network can be controlled by someone to hack the computer or cellphone you are using, I suggest storing phrases offline recovery so it's not easily accessed by scammers.
