I just use biometrics on my phone, and enable panic/lockdowm mode option in the power settings. Set your master password in the manager to some really long string and print it out and hide it somewhere in case you really need to use it.

And yeah, this won't protect your from like the FBI or CIA if they decide to just come into your house, but 90% of security is just making sure script kiddies can't get your login info lol
