Every time I get new service or new card, I get new user name and new PIN code. As it is written in many data security manuals, never store your codes next to computer, mobile device or similar places, where it can be found. it is also written that newer
use same user names or passwords to different places.
Problem is that I will forget passwords and user names. Especially when not using service every week. Like my third credit card, haven't used to many times and have no clue what is PIN code for it.
I have seen some new innovations where I can store all my valuable information and use is while browsing online. It can be like online master vault for usernames. But it works only partly. For example if I register to that system using my company email address
and then move to another company, I have no access anymore to receive those old emails. Or if I use my current gmail- address, do I really trust that it is not hacked.
Some time ago I started to think if only one PIN code I have created could be part of my solution. Under that PIN code I could store all my other PIN codes, account numbers for direct debit, e-invoice address, phone numbers etc. When I need my information
for example accepting new SEPA Direct Debit payment with merchant, I fill out my information to online platform, add my PIN code and then use verified online method. When I am identified with my e-card ID or similar method, same time another request is send
to one common server, where my PIN code is verified with my given bank account number. These informations are provided same time to merchant, but merchants information is send to my bank to notify that this merchant will soon debit my account.
Or this could be used to shop online. Instead of giving my card number or my card PIN number, I just give my own created PIN code and I am verified same way as required by Visa/ Mastercard secured solution. When everything is OK, merchant will get my card
information, but my bank would get information that this merchant will debit my account soon.
With this system, there would be two layers of security, but same time end users would have easy way to purchase or do business online.
Of course, who will control this master data base with all the information I have given? That is the big question.
