The issue described here started happening to me recently: https://www.googlenestcommunity.com/t5/Apps-Account/Why-is-G...
Summary- Google has added a “match the numbers in the app” style 2FA to YouTube. Makes sense- their video monopoly means that for many iOS users like myself it’s the only Google app they’ve got. Except…
1) It’s the default, and there’s no apparent way to change it, or even turn it off. This is annoying- I prefer TOTP since it’s more secure. There’s a Google Prompts section in the 2FA settings, but it says that I don’t have any supported devices. This actually makes sense, because
2) It doesn’t f*king work! Ever since they changed it from “press yes” to “match number”, the screen opens in the YouTube app and then loads forever. Which means I’ve got a spurious notification on my phone, a screen to dismiss next time I open the YouTube app (or several, because for some reason they can stack), and two extra clicks every time I log into Google on a new device.
Actually, I lied earlier- there is one way to disable it, and it’s to DISABLE ALL 2FA, as you can see people doing in that support thread. I honestly don’t blame them, but clearly less 2FA was not the plan of whoever’s idea this was. Speaking of support forums- I don’t think anyone at Google reads them, but they do read HN :))))
