After 11 years of life, Google Authenticator has added cloud backups for OTP keys in version 6.0.

Google Security Blog: Google Authenticator now supports Google Account synchronization

This is surprising news to me, because historically Authenticator had no way to backup keys by design. Here's a 2017 quote from a Google engineer who maintains Authenticator:

There is by design NO account backups in any of the apps. ^[source]

This design choice always made sense to me, as the point of 2FA is that you've got (1) something you know, and (2) something you have. The second factor should be tied to a physical device. If you lose the physical device, the second factor should be gone, and you'll need to use one of those 10-ish backup codes that we all definitely keep somewhere safe. I'm quite befuddled that Google is reversing this design choice and walking back their previously strong, security-centric design for the sake of user convenience in the case of a lost phone. I used to advise my friends and family to choose Google Authenticator over Authy for this specific reason.

We're excited to announce several updates to ChatGPT! Here's what's new:

• General performance: Among other improvements, users will notice that ChatGPT is now less likely to refuse to answer questions.
• Conversation history: You’ll soon be able to view past conversations with ChatGPT, rename your saved conversations and delete the ones you don’t want to keep. We are gradually rolling out this feature.
• Daily limit: To ensure a high-quality experience for all ChatGPT users, we are experimenting with a daily message cap. If you’re included in this group, you’ll be presented with an option to extend your access by providing feedback to ChatGPT.
  To see if you’re using the updated version, look for “ChatGPT Dec 15 Version” at the bottom of the screen.
