I want to enable 2-factor authentication on my Adobe account but using TOTP that is supported by many 3rd party apps (Google Authenticator, Microsoft Authenticator, password managers, etc.). I use my password manager to manage all of my TOTP 2-factor authentication. I do not want to have to use and manage the Adobe Account Access app for just this one single account. I see several references of this being supported for the Adobe account:

but my account settings page is missing the option to enable this type of 2-factor authentication. I only have the options for the Adobe Account Access app, email, and SMS/phone text. How do I enable 2-factor authentication for use with 3rd party TOTP apps?
