Perhaps the best form of security is providing no indication that you own Bitcoin. Tell no one that you have some. Outside of this, there is really no guarantee that you are safe.

Security is also man basic needs on earth because it’s very devastating and most times deadly when someone steals our valuables. The reason I suggest for a confirmation code for every transaction is simply because bitcoin and most crypto are decentralized making it almost impossible to recover lost coins. There should be a confirmation code sent to our email or phone number during transaction in crypto wallets to originally prove the transaction is being performed by the real owner of the wallet, once  the confirmation code is received via gmail or any other means and has been copied in the appropriate place. This action will automatically confirm the transaction in the wallet.

I have had reports of people complaining of their lost wallets. some where asked to provide the pass codes of their wallets forcefully at gun point. In my locality now this is the modern age robbery. People are much aware about bitcoin and are using this means to steal from innocent bitcoin enthusiasts. My friend was a victim couple of days ago as she was robbed of her valuables and the robbers went further to ask for her blockchain password which she fearfully provided and immediately her bitcoin was wiped away from her wallet. This is so scary and threatening to bitcoin enthusiasts.

OP do you create fake story?

If the robbery only know the blockchain password, how can he able to log in? He need to confirm the confirmation link send to your friend email.

Bitcoin wallet, using a hardware wallet will provide those security measures,
needing a passphrase or series of numbers to access the device, sending a transaction
needs the owner to verify each transaction.

Personal security hasnt changed, we need to be vigilant and try to keep our posessions
secure particularly smartphones as they hold so much information. Broadcasting
ownership of Bitcoin publically IMO is a no-no.

Being able to defend ourselves is important, most thiefs are opportunistic.

Physical threats against bitcoin owners have happened before and we've probably heard of them being discussed several times on this forum. This is not a new story even though the time and place of the events are different.

Get a Second phone. Most people only owns one smartphone at a time hence there's a high chance the robber wouldn't be able to think you have another one. Worst case scenario is if they thoroughly check your bag (get a bag with secret pockets!) although IMO most robbers are in hurry and so I don't think this is something highly likely.

If you can, leave your main phone at your house. That would provide better security.
