How do computers make any color using red/green/blue, when paints make every clor using red/yellow/blue?o

It's just the concept of additive color mixing vs subtractive color mixing.

Adding pigments together will ultimately create black. While adding more light together will ultimately make white.

With pigments you're taking away from the color space. You paint red to subdue all other colors except for red.

But you use red light to make sure red is better seen.

Can someone give me a good rundown on how to keep my accounts safe but also not locking myself out ?

I only know 2 passwords.

Bitwarden for all of my passwords. No OTP in bitwarden.

Bitwarden admin email's password is not in bitwarden, it's the only other password I know.

With all accounts supporting webauth I use yubikeys.

For accounts that don't support webauth, I use Aegis that's password secured with a static password on my yubikey so even I don't know that password.

If I lose all 3 of my yubikeys, them I'm SOL.

Help me with a rotating firesafe data backup

For my 1 part of the 3-2-1 plan, I have an encrypted copy at my work, and I also ship an encrypted copy to a trusted friend.

My work copy I can always get in a few minutes, my friend is if something big happens locally.

I have 4 cold storage disk, 2 are rotated about every month. And the one that's with my friend is rotated once a year.
