Will someone have access to your wallet without your device but the person manage to see your private keys and copy them without your knowledge. Will the person be able to withdraw your money or change password and block you from having access to your wallet?
The risk is very big if someone can have access to your wallet, all the assets you have can immediately change hands without you knowing it. It is highly recommended to store the seed phase or private key in a safe place. Besides that, always avoid phishing, malware, applications containing viruses or the like that can threaten the safety of the assets you have.
Cases of loss of assets have happened before, hopefully this information can be a lesson for Op and also other users to further improve Wallet security and avoid phishing or the like.
