Google has updated its 2FA Authenticator app for iOS with a new account transfer feature that makes it much easier to transfer two-factor authentication codes to a new iPhone.
2FA adds an extra layer of security to your online accounts by requiring a randomly generated six-digit code after you've entered your password. Google's app generates codes for your accounts on the fly, but until now the process of transferring accounts to a new iPhone was time-consuming and involved multiple steps.
Thankfully, that's no longer the case, and you can now select which accounts to export by tapping the three dots in the top-right corner of the app and choosing Export accounts.
After you've chosen which accounts to export (you can export up to 10 accounts at a time), the Authenticator app will generate a QR code. Scan this code using the Authenticator app on your new device, and the chosen accounts will be automatically transferred.
In addition to 2FA export, the latest update to the app also adds a refreshed interface and Dark Mode support, which respects your systemwide settings.
Remember, if you buy a new iPhone to replace your existing one and you use the Google Authenticator app, you should transfer those accounts to your new phone as soon as possible, because without the 2FA codes close at hand, you could find yourself locked out of your online accounts.

This week marks the 10th anniversary of the Apple Watch, which launched on April 24, 2015. Yesterday, we recapped features rumored for the Apple Watch Series 11, but since 2015, the Apple Watch has also branched out into the Apple Watch Ultra and the Apple Watch SE, so we thought we'd take a look at what's next for those product lines, too.

In 2027, Apple is planning a "major shake-up" for the iPhone lineup to mark two decades since the original model launched. Gurman's previous reporting indicates the company will introduce a foldable iPhone alongside a "bold"...

While the so-called "iPhone 17 Air" is not expected to launch until September, there are already plenty of rumors about the ultra-thin device.

Apple is preparing to launch a dramatically thinner iPhone this September, and if recent leaks are anything to go by, the so-called iPhone 17 Air could boast one of the most radical design shifts in recent years.

Too few, too late. Authy has taken the spot as a decent and easy to transfer 2FA application with a much better approach of using iCloud storage for backups and restore. Move along, Google - you had your time.
I use Microsoft Authenticator now (I used Google Authenticator for many years and Authy for a year or two) and I'm very happy with it. Many ways to add your codes, backups (if you want, you can disable it), plus password-less login to your Microsoft account which I initially didn't think I'd use but boy is it a time-saver. You can also perform several security related tasks on your Microsoft account through the app. For someone like me with one foot in the Microsoft world and one foot in the Apple world it's perfect.
Yep, I'm in the OTP Auth camp too (https://apps.apple.com/gb/app/otp-auth/id659877384). Hassle-free syncing across devices, Safari plugins to make entering the codes a doddle. I don't know why people would use Google's version. Even this solution requires that you have the new and old phone at the same time, so doesn't work for trade ins, or replacements of lost/broken phones.
I appreciate not storing the keys in the cloud is more secure, but come on, they're stored encrypted in iCloud with a key Apple don't have. I doubt anybody with the power to hack that is particularly interested in pretending to be me on MacRumors forums!
