With wero you must have play integrity and you can't even have developer mode turned on which is frankly ridiculous. I don't know of a single app that requires that. Source: https://support.wero-wallet.eu/hc/en-us/articles/25599098295...
They had a great opportunity to make an ecosystem not dependent on google and apple and they utterly failed. You can't even log into it on the web, you must use the app.
A step backwards, in my opinion. I'm not sure what this system adds that sharing an IBAN doesn't, but then again Tikkie's conquered that market pretty quickly for some reason as well and each bank has had to copy that feature individually.
There are separate sections for "Wero in your bank app" and "Wero in the Wero app", so I assume the Wero wallet won't be mandatory
It would be a pain if your bank wouldn't provide direct Wero integration, though.
