Is it possible to set up 2fa/yubikey with only with a windows laptop?

Always happy to help. :)

But none of my accounts {bank, credcard, invest, or stock) seem to support it !?!. They only seem to support sms 6 digit code.

Unfortunately, this does seem to be the state of things in some areas, especially the financial industry, where best practices (strong password + two-factor authentication) aren't always implemented in favour of something else. We wrote a blog post about that a while back which is still, regrettably, true today:

☞ An open letter to banks

Although we say "banks", you can safely extend that to many different types of financial institution such as stock trading platforms, investment management firms, and so on.

I'll look into Amazon

Amazon does work with industry-standard two-factor authentication, so you can use 1Password to generate your one-time passwords.

An extra point: It's important to distinguish between using two-factor authentication to access your 1Password account, and using 1Password to generate two-factor authentication codes for other websites. You can find the details of both of those below:

• Turn on two-factor authentication for your 1Password account
• Use 1Password as an authenticator for sites with two-factor authentication

I'm a little overwhelmed by all this (gee, can you tell)

It's a lot to take in! This is especially true if you're setting most things up from scratch. Feel free to throw any questions my way here – if I can't help with something specifically, I'll try and point you in the right direction. :)
