You could probably get a couple, and then set it up with https://landing.google.com/advancedprotection/. Google's Advanced Protection is the best you can get right now, but you probably don't need it. My philosophy is I can't properly tell people to do things for their security if I don't do it myself and understand the pain points. For the record, I don't use it. Too inconvenient when I'm on a ship and can't log in to things.

A brief note: Cell phone text messagesaka SMS are commonly used for multifactor auth. These are not great, because a) someone can steal your phone number and get the texts sent to them https://www.wired.com/story/sim-swap-attack-defend-phone/ b) intercept of text messages https://www.theguardian.com/technology/2016/apr/19/ss7-hack-explained-mobile-phone-vulnerability-snooping-texts-calls

However, those things are not in your threat model unless you are famous or have cryptocurrency wallets.

Another note: Just because you have 2 factor doesn't mean you can't get phished for it!
