A Tentonhammer article posted Wednesday warns of potential problems with your iOS device Authenticator app that could result from upgrading the device’s operating system to version 7.
I must admit, despite being a techy, I’m very lazy when it comes to my own tech and especially my iPhone. I rarely follow the IT press anymore so would only notice a new version of iOS when I got around to running app updates, which I do very rarely.
Years ago I ran foul of this kind of problem, I swapped phones in a hurry without thinking about what apps I had loaded – this naturally broke my Authenticator since it is phone specific. Since learning from my mistake I make sure to de-attach these apps before upgrading – it’s worth the extra 5 mins of admin to be safe!
