THE FRUSTRATION OF PC ONLINE FNB BANKING

I was unable to login today on my PC for online banking, the reason given "wrong username/password". A definite glitch in the system but to facilitate my login I went through the unnecessary rigmarole of changing my password. However, when I tried to login again with the "successful" password change, the same message - "wrong password". FNB is aggressively pushing their banking app which is incompatible with PC banking, so effectively forcing clients to use their phones/tablets to bank. Phone banking is not an option for me since I am elderly with limited vision and fine motor control to input numerals. So, is my experience today a deliberate strategy to force me to download the app and to abandon PC banking?
