It's not just about the security of the device used, but how the user himself or herself maximizes those security options correctly.
If you continue to feel that nothing keeps you safe, you need to see how a security can be breached,
you need to know cause and effect, so you don't have to be too skeptical about the security you use.
Like storing seeds online, it can actually be a safe place if you can maximize that security by not directly using the account for other risky activities.
And the key to all that security is up to you.
Don't be too skeptical, that's not good either.
I've read in the news that people who are too skeptical are very vulnerable, and even those who make more mistakes,
overthink the big things but ignore the little things that can make problems with security.
