YubiKeys are pretty great. I use it. I hate when you have to authenticate via sms, and apps are slightly better.
If you get a YubiKey, you can use it to authenticate into your password manager. I know some people who do only that and they use the randomize password function that’s long and would never be human memorizable.
If you don’t do that, support for the key is listed on their website. There’s enough support on various platforms to make it worth it. But I was surprised the list was so small. I do wish more financial institutions would get with it. Most of my banks only do sms.
