I’m linking this draft discussing BFF from oauth perspective.

With significant advancements in AI technologies, including solutions like ChatGPT/Bard, I am considering this issue of multi-platform from a standpoint of AI. If an application has been developed for a major platform, adapting the same applications for other platforms could potentially be managed by Co-Pilot. For instance, I can already create applications with the assistance of ChatGPT.

I’m gonna wait for them to be able to solve a sudoku first, before daring to give them any non-toy code.

Agreed! I don't use that feature at all for the same reason. I don't have my key with me at all times.

That is sort of the idea. It's a relatively cheap authenticator that can be bought to provide 2FA for added security for your services. You can integrate it with Gmail, Mac Logins, etc.

Yes, I'm interested in general adoption and whether general populous would adopt such a 2nd-auth if presented as a fashion item (i.e. make the authenticator more accessible).

In the UK Barclays and NatWest (maybe others) offer a card reader for 2FA for banking transactions, I assume based on something like HOTP.
