MFA is a requirement of the revised Payment Services Directive (PSD2) in the EU and many banks use their apps for authorising online card payments. Its also common to use apps as 2FA for logging in to online banking or making bank transfers.

There can be alternatives in some cases (some banks offer code generating card readers, for example) but for personal accounts in particular, it would probably be difficult to operate without banking apps.
