Keep in mind that a USB is also inconvenient. If you're using a non personal computer and needed to access your accounts, you likely wouldn't be able to connect the USB to your phone to find your passwords. Most password managers have apps that you can use.
Sorry for the late response.
Actually, I use Kingston's DT Locker+ G3 Secure USB Flash Drive with Cloud Backup which gives me top-notch security with their DataVault Security password protection software where, once set, you cannot derive the data without entering the password because it encrypts all the data inside the USB and only allows you to see it if you know the password. The only catch is that you need to remember the password because if you lose it, you lose the entire data as if you try to set up a new password (and even if someone who stole your USB tries to do it), it will immediately wipe off all the data inside and open the USB with a completely new session for the sake of maintaining security of the data in USB.
Unluckily i havent able to find this usb on my local marketplace.This is what im looking for in regards with extra security where i do love that auto-wipe feature when someone do tend to bruteforce it out.
