Well the best way to key your bitcoin wallet safe is to keep the recovery key or private key save from any other person including your dear ones such as close friends and family. It is not everything that people around you must know about you especially as it deals with your asset. We've seen cases where brothers go into battlegrounds simply because of inheritance that has been kept for them to take.
Some humans are selfish by nature and they have this thing within them that motivate or instigate them to go that route so, the best way to avoid somethings is by keeping them private to yourself which includes your seed phrase.
Your private key is so important and delicate to the level that you are advised not to upload it anywhere online in any cloud storage. Instead you should have it stored offline and keep it up to yourself. There are a few ways you can store your private key offline which is through hardware written on paper, through custodial and noncustodial cold wallets.
The custodial wallets are when you allow your exchange company to store the keys for you whereas in noncustodial you do that yourself. The danger in allowing other company's store it for you is once their server or database is hacked into, your asset is probably gone forever but custodial wallets can be of advantage to small and new bitcoin users who have meager resources on their wallet.
On the flip side, the noncustodial wallet is an example of Ledger Nano X which you make use of yourself to take care of your key. Whichever one you do have their advantages of disadvantages but the best is to always have your private key secured in an offline physical storage where you can always access in years time.
