Stichting-Opel-Super-Six-Golden-Wolf When someone is logged in on the account and someone else tries to log in, give the newer attempt a message (eg: Unable to log you in as <NAME> is presently logged in).
Fictional scenario I see happening now: a scammer gets access to my account, I notice unusual transactions (push notifications) and want to log in to reset my login code / change my PIN code etc. But, I can't log in, because the scammer is still logged in. 🙈
I'm not sure as I don't run a bigger business or something, but how often will this really occur? Will multiple directors be checking the accounts at the same time frequently? Can't you (just as a workaround) setup connects to a personal/free account to manage the money? And for more "configuration" stuff you can then use the actual Business login. 🤔
