Not picking on anyone, but I just saw someone asking devs not to use "2FA" in user messages, and instead use "two factor authentication."

2FA is 3 syllables. Two factor authentication is 8.

From my #a11y use case, 2FA is an accommodation.

I would argue that there's already an HTML way to solve this problem, and that's the html abbr element with the title attribute.

#a11y #html

: The Abbreviation element - HTML: HyperText Markup Language | MDN

The HTML element represents an abbreviation or acronym.
