Most people have access to Google Auth and it would make more sense to go with that if 2FA was to ever be added to Bitcointalk.
I made a suggestion to add 2FA/MFA of some sort recently and I think the conclusion was it's planned in the next version of forum software.
Better to just wait and watch.
Exactly my thoughts. 2FA software is good enough, and those hardware stuffs are best reserved for those FI-related industry jobs.
