The without recourse is the part that matters... With passkeys or 2FA she's at risk of having to wait a day or more to go to the physical location (if there even is one, digital banks are huge in Latin America), with passwords she can just check her notebook the same night and start the recourse through official channels. I know she could just call the hotline, but if 24hr customer service guy can get you in your account same night then the bank is too insecure anyways
