Been using Barclays online for years on the PC with few problems.
Decided to install it on the new phone to use it for contact less payments, etc. Any other banking I'll still use the PC.
Phone is set up for finger print 'pass'.
Worked OK - but on trying to log in the other day it demanded a 5 digit pass number as an additional check. And the only 5 digit number I have is the original from my online banking - which it refused.
