I would rather suggest changing your wallet frequently.
That's not really required if you use a cold-wallet to store most of your cryptocurrencies.
Not only is it not required, it's poor advice. If your security practices are poor and your wallet is insecure, then changing to another insecure wallet which you set up with the same poor practices won't help you. In fact, it might make matters worse - if you are constantly setting up new passwords, you are more likely to start writing them down or storing them electronically because you can't remember them.
One securely set up wallet is far superior to any number of insecure wallets. If you are unable to set up an air-gapped wallet yourself, then just buy a Ledger or a Trezor.
