How do I enable 2 factor or multifactor authentication on my AARP login

[RobW142529]

How do I enable 2 factor or multifactor authentication [ Microsoft authenticator or Google authenticator ] on my AARP login. Currently it sends a text to my cell phone but I'm wondering if there is a way to setup one of the authenticator apps that has an ever changing one time code. 
Microsoft authenticator or Google authenticator is what I use for other accounts when available. https://support.microsoft.com/en-us/account-billing/about-microsoft-authenticator-9783c865-0308-42fb...
Thanks for your assistance!

Great question, @RobW142529. The multifactor authenticator we currently use to secure our members accounts is through text message only. Here you'll find an article with the steps: https://help.aarp.org/s/article/rewards-verification?cmp=SNO-LITHIUM---&socialid=14197088719 - Diana G.

This is unfortunate, and outdated. SMS is the least desirable 2FA solution currently available (other than not using 2FA at all.) AARP should seriously consider upgrading to either TOTP, hardware keys, or (ideally) passkeys for more robust security
