making my own food out of what I have in the pantry is consuming a lot of my time between shifts
Make sure you make very large portions. Cook enough pasta for 5 meals, then put 4 in the fridge. Those four reheat quickly in the microwave. Beef stew? 10 portions. Steak? 3 portions. Same for everything else, don’t just make single portions, make extra then eat it later as a quick meal. Cooking takes significantly less time this way. And is way, way faster than waiting at a McDonald’s.
The gold standard is providing something you know (a password) alongside something you have (an OTP or fingerprint). This is two-factor auth in a nutshell.
You leave fingerprints and images of your face everywhere you go; and in the case of someone spoofing those, there is zero way to change either. Such public information is not the foundations of a secure system.
And a PIN is just a shorter, shittier password. Why the hell would we replace a normal password with the least secure, most shitty version of a password?
