The remediations recommended are:
- alphanumeric passcode
- different passcodes for financial apps
- not using the native password manager
- not storing credentials for financial apps in any password manager
- if you have to enter the code do not do so in public or hide it
How an alphanumeric code helps defeat this adversaries is beyond me, because the video describes the attackers recording the code from over the shoulder.Why MFA or tokens are not recommended, I do not know.
