Can I do banking on someone else's laptop?

In principle, yes, because access is only possible with a photoTan or SMS. The safest would be using your own smartphone.

Technically no problem, you only need internet access. The registration is then done with YOUR user data.

BUT: you never know if the other laptop is safe. It could be Trojans, keyloggers, etc., which then spy on your access data. If the owner handles it carelessly, there's a risk. So I would advise against it. Use the smartphone app in parallel, because you know exactly what's going on. Greeting
