But as soon as browsers stop autocompleting fields marked with autocomplete="one-time-code", won't website developers start marking _all_ input fields with this tag? After all, why do people put autocomplete="off" on input fields anyway?
autocomplete="one-time-code" causes a different type of autocomplete behaviour, it doesn't disable it. Specifically for example it will suggest a one time code you received by sms if one was recently sent (on mobile at least).
