That depends. Consider that some businesses, including banks, have apps that had to be registered on the device. ie the bank can recognise the device and reject other devices that are not registered to the account.
Open app. App triggers an SMS 2FA code to input to the app. Why – The device is registered?
Many devices recognise some incoming 2FA texts and automaticlly insert it into the requesting app. Security? How is that ‘value added’?
Just yesterday I tried to register an app for an account I had been using on my PC for months. Open app, app triggers email to approve it for the account, but by the time I fiddled from the app to email the link expired. After a few tries I intercepted the email on the PC and got it done. Easy?
Further many people are dexterity or vision challenged. Phones, sorry some devices, are challenging to use because of that. Even able bodied can struggle mightily operating their device in the sun and the wonderful voice commands can be wonky depending on background noise, language, and an accent, let alone actually causing all the necessary functions to occur.
It does not add value to make generalisations using ones personal experiences and expect it applies to everyone else in all or even most situations.
As for cost, My ‘landline’ costs me nothing unless I use it. It is a free part of my NBN package. My aldimobile pack is $140 p.a. but most mobile plans are $20-30 pcm up.
Our mobile coverage is another topic to itself. Actually a number of topics on the Community, a recent one being
Basically if there is no signal even the best mobile with the most capable user is not going to ‘get it done’.
